After making a purchase of a few items with chain reaction and getting a £10 discount, I started reading reviews, which got me worried. I paid for 4 day delivery, after checking my on my order on day 2 it still stated processing which got me more worried even if I was going to receive my items, so gave them a message on live chat, they responded instantly and reassured me my item would be here within the time scale. The next day I had a knock at my door it was the hermes courier with my order a day earlier than expected, all correct and packaged perfectly. A* service.
