Bad service

Samsung S5 was taken to Vodashop Middelburg Mall, because the screen went yellow. This was on the 17th of December 2014.They told us it would take 2-3 weeks to repair. After a month we contacted Vodashop and they told us that they haven't received the phone back yet. We phonedwitbank and they said that they haven't received the phone.Middelburg phoned us to tell us that the phone was in Witbank but they forgot to book it In. After another week we went to vodashop and the phone was still not back . I spoke to Mark in wit bank and he said they arejust fitting a new screen and he will send the phoneback the next day. A week later the phone arrived in Middelburg .We went fetch it. when Billy tested it, the phone didn't even turned on. It was send back to Bennie and Billy said that he will get it back the next night. After more than a week Billy phoned to say ty don't know wat the problem Is and they send the phone to Samsung. All we get now, is him passing the buckand Samsung phoned us to rate their service, but we still not have the phone back. Can we pleaseget our fixed phone bade or a new one Its been 2 months alreay .Poor Poor Poor service from Vodashop!
