Repair of a handset

It has been full 5 weeks that I have sent my faulty handset to MTN Alberton mall and I have not received it back. When I first handed it in with all the accessories, the staff member who assisted me just took the handset and promised to send me an email confirming the receipt and the expected date of completion of the repairs. Seeing no response from them I went to the outlet after 3 weeks, only to be told that I had to deactivate the \Find my Phone\" feature before they can repair it and the manager promised to get back to me after that. I did that within an hour after leaving the outlet. I never heard from anyone since that day. To date it is now another 2 weeks since I was promised to be contacted. I then decided to skip work for this morning and went there to find out exactly what the problem was. This was after several vain calls to at least get feedback from the manager. When I spoke to the manager on this it was like he is seeing me for the first time in his life and I had to start explaining from the beginning. I was promised to that might get it by next week Wednesday. 5 full weeks of no response is just pathetic!!! I never had such poor service with Vodacom. "
