VERY POOR SERVICES POOR

I took a contract with Telkom in 2018. Mid July this year my phone started giving me software problems , it would just switch off on its own and the camera was not working some of my apps where not working , so I decided to take it in for repairs at Telkom branch in Mthatha BT Ngebz mall and the service I received was just bad like -10 kinda bad service. When I went in to check on my phone at the shop no one knew anything about it they didn’t know where my phone is and if it has been repaired or not or if the repair center received my phone or not and when I asked how is that possible instead for them try to help me out and try and locate my phone they gave me a number that I should go and call myself , instead of picking up the phone and calling the customer care or repair center they just said straight to my face that if my phone is in for repairs the is nothing they can do for me because it goes to a different department and I’m the one that needs to call that department they don’t deal with it and the number I was given doesn’t even work because I tried calling it at work like 5 times, and when I want back to the shop they said they can’t help me with anything but my phone is with them I just didn’t understand that part, I called customer care and I was told customer care has a different system and only the shop can help me find my phone. I went back to the shop and I told them what the customer care guy said and asked them to call customer care and I was told they won’t do that I should call myself. Then Friday when I went in to check for the last time I was told I will get my phone after two months but they didn’t even check or anything it’s like they don’t care about you after you buy a product from them because the service is poor very poor , I work in a bank I know good n poor service and the service I got was just very poor
