Pathetic.Took my husbands phone in for the 3rd time with the same problem.I asked to speak to a manager.Tariq is the floor manager.Took the phone,tried charging it,saw that the phone does not switch on while charging,it only vibrates the whole time.Went to speak to Gus,electronics manager & came back saying they think its the mother board.BUT,THE MOTHER BOARD WAS REPLACED THE 2ND TIME I TOOK THIS PHONE IN.Gave me a form to say that he took the phone from me & he will phone me with the job number.I explained to him I need to know whats happening as I stay far.Tariq never phoned me.I had to pull over on the side of the road to phone.100% mission to get hold of anyone let alone Tariq.Finally got put through to Jeffrey.He took my number to find out from Tariq whats happening.Got back to me 20min later (me still on the side of the road)
