Rude and gave the impression of not willing to help with a code that wasn’t processed.

I valued customer or so many years treated like a nobody- charming!
Feedback Response: The code you provided to our operator when you placed your order (WGA192 - now expired) gave a 15% discount from a minimum of £20 spend. The WGA192 code was applied to your order, but because your order total was £19.18, no discount was given. I'm sorry if you feel that our operator couldn't assist you further, but they don't have access to the offer-codes so wouldn't have been able to assist you further. We provide all details of any minimum-spend requirements with codes and promotions so that our customers can assess whether the promotion is one which they wish to take up. We greatly value all of our customers and I'm very sorry that you felt undervalued here. Thank you for your ongoing custom with Just Vitamins.

Feedback Response: Sorry to hear that you are unhappy with the taste of this supplement, but this should not affect the quality.

Kind regards, Ian - Just Vitamins Customer Team
Service rating: Just Vitamins have a great range of products at a competitive price. Their website was easy to navigate and I found what I wanted immediately. Delivery was quick and the product was well packaged. Time will tell how the product performs but I have no reason to think that I will not be happy with it. I would recommend Just Vitamins and I will no doubt buy from them again.
Product: I have not used the supplement for long so it is probably too soon to determine whether it works or not but the ingredients are good so I'm sure I will be happy with it. I'm taking this supplement to help the circulation in my legs and ease my varicose veins.
Service rating: Quick delivery, thanks.
Product: Good supplement. Fast dispatch
Fast delivery, always excellent service
Great product for a good price and fast delivery. Thank you.
Good and fast service
The person who took the order was extremely helpful. The order arrived very quickly. The prices are also very competitive.
Service rating: I have said it before the postage service of the products ordered from the UK to Europe is excellent. Goods are always withing 7-8 days upon placement of order. I am in fact repeating myself. I guess you can say standards have not dropped.
Product: I have stopped taking them for a while. I.e. a short break.
Service rating: Very good- as usual.
Product: Very good packaged well..
Delivered product promptly, easy to order, no problems.
Service rating: This is my first purchase from JustVitamins. Great product, value for money and speed delivery. I will be trying other products from this company
Product: Great product, it definitely works
Great service
Service rating: Price, quality and delivery are generally good. However, they are often 'Out of Stock' for long periods on some items which requires my sourcing from elsewhere ... not good for them as I prefer to order everything from one place!
Product: Very effective ... but I need it with the same dosage in L-Carnitine 1000mg which is too often 'Out of Stock'. They do have L-Carnitine 500mg but this works out at twice the price... so leads me to source elsewhere!
Service rating: The website is user friendly, the ordering process simple, the information on the products is good. Delivery was quick, packaging good.

Been on the pills now for a couple of weeks but have noticed no discernible change which is a little disappointing
Product: Taking this with Pycnogenol which combined is reportedly a cure or helps alleviates symptoms of Erectile Dysfunction. Been taking for two weeks with no discernible difference. So very disappointed at this stage but will complete the 90 day programme
Very efficient and good service. Received products right on time. Quality very good.
Quick steps, good packaging, Will definitely be purchasing again.
Quick reliable delivery and good product
Service rating: Fast Service
Product: Good fast Service again yet again
Service rating: Very quick service, convenient in postal delivery
Product: Feeling more energetic, using it to increase energy throughout the day.
Service rating: I didn't receive my package and didn't get a refund either
Product: I didn't receive it and the company didn't issue a refund either
