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.

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.
