Samsung NO-service Center

My daughter’s phone went in to be repaired in September. Unfortunately, I do not have the precise date as that paper with the date was handed in when I collected the phone after repairs. I happened to be passing the Samsung service center in Tygervalley where the phone was handed in and I took a chance to enquire about the phone only to find out that the phone was there, only they neglected to notify me. The phone was fixed or so I though. Unfortunately the phone was loaded with the incorrect service provider. This caused the phone to reject the sim card. So the phone had to go back to the service center. The phone went back for the second time on the 03 October. Since then I have made numerous unsuccessful trips to the service center in Tygervalley. They do not have the phone, then they try to phone the service center in Century City but get no reply. They did get through twice and on both occasions I was handed the phone to speak to the call center myself to explain the problem. The first time I was told they do not know where the phone is. Sorry. The next time I was told by Raisa that they just received the parts and are in the process of fixing the phone and the phone will be available for collection the next day at the latest. I told her that I did not believe her story about the parts and it was just another excuse because the phone was supposed to get different software. So they lie to you about parts in the hope to win time. SOOOO, not acceptable. But she did promise that the phone will be returned before the end of Friday afternoon. That was three weeks ago. Since then I have spent countless hours, effort, phone calls etc. trying to get the phone back. I have been to the service center at Tygervalley nearly every second day. No luck. The assistant just tries to phone the service center in Century City while you stand there waiting and have to stand there watching him reading his emails and checking his phone messages. The service center NEVER even answers! The one time there was another customer that has been waiting to get feedback for an hour and a half. Really??? I have phoned Wayne Peters and he promised to sort out the problem. They did phone my daughter last week Friday, interrupting her in class, to tell her to collect the phone from Canal Walk. She asked them to send it to Tygervalley. They phoned again on Monday and on Tuesday to say the phone is fixed and needs to be collected. BUT IT IS NOT THERE. I have tried phoning Wayne Peters again and again but the calls just get dropped. John Preiss has been trying to help by speaking to Wayne Peters and Ricardo (I don’t know what his job title or surname is), but no luck there either. My husband was there on Saturday to ask regarding the phone. He asked for the email and telephone number for the regional manager, and was given the number and email address for Wayne Peters. The staff at the Samsung shop told him that Wayne Peters is not the regional manager. The assistant got quite a mouthful about lying again when asked for the regional managers email address. He said that he do not think he is allowed to give out the information. If we cannot contact the management how are we as customers supposed to sort out the problems???? I have been told that I will have feedback from the managers as to where the phone is by John Preiss. That was three days ago and still nothing.
