EXCELLENT!! THEY SOLVED THE PROBLEM VERY QUICKLY ! I ordered from them first time and I am very satisfied. The economy package arrived faster than I expected. By mistake I received a vitamin with a lower IU content than I ordered. I sent them an e-mail and received a reply in a few hours. They apologised for the mistake and ordered a courier who just today collected the package of vitamins I had not ordered and I have just received a package with the vitamin I was expecting. Everything was done in 3 days ! I really like the way they dealt with the customer when there was a mistake and how quickly it was resolved.
