Bought a HTC one m9, on contract with a £100 upfront cost... At the time of buying I was put off by the fact that the store only had gun metal grey and the phone was almost identical to my previous phone the HTC one m8.. It was the sales assistant's assurance that If I got the phone I could exchange it no problem the the following Monday... I found out that not only did the shop assistant have only a fraction of the enthusiasm when dealing with me when I returned to exchange my phone but his assurance turned out to be bogus... I'm now stuck with a phone I don't want, and all the shop keeper could give was a shrug and half hearted sorry..( crouch end branch of c.p.w.h)
