GymAndSpin reviews and complaints

I have ordered a pair of shoes from www.gymandspin.co.uk and my order arrived in a timely manner. I really liked the prices and customer service seemed nice. Everything was fine until I actually received my order and saw my shoes. They looked worn out, quality was terrible, soles were dirty! When I contacted GymAndSpin customer service they promised me a replacement. They also said that I don't need to return the defective shoes. Several days later they gave me another tracking number and said that shoes were shipped. Tracking umber was not working and these guys just stopped answering. I'm still waiting for my replacement shoes but I think that they never sent me anything. I would like to get my money back.
