I have used CeX in Kettering for years and the service as been excellent, I was in wellingborough shopping centre today and noticed your store there so I popped in, after looking around I decided to purchase a mobile vecause id smashed tge screen on my current phone i saw a Samsung A3 mobile which you had for sale it stated that the mobile was locked to 02 network so I asked one of the assistance if my sky SIM would work because sky use the 02 network I was informed that it would so I purchased the phone, and then went straight to the mobile case shop and purchase a screen protector. having got home I proceeded to transfer all my data over having done this I tried to use the phone and it said I wasn't logged on to the net work. I call sky and they told me I need to call 02 and see if they could sort it 02 told me to call Samsung, samsung told me to call sky I was going around in circles so I went into an 02 shop in the same centre as your store they informed me that the phone was locked to them and only an 02 SIM work in this phone. I then took the phone back to store only to be told that they would have to preform some sort of test before they could do anything, I informed them of my rights and raised my voice a bit and they keep me waiting for about twenty minutes before I got my refund, they said there nothing they can do about the protector I purchased so I've lost £5 but you have lost a good customer I will never use your stores again your staff are rude and very unprofessional.
