Poor customer service

Hi my name is Randall Jonas I have 2 contracts by MTN. 5 months back I took a Samsung A55 phone on contract by MTN for my wife, a few weeks after using the phone, we pick up that we had network problems with the phone but we just ignore it because like always we were thinking just that the network and the area we were in was maybe bad but as time went on the problem become worse so I told my wife to take it to MTN in waterfront where she work close to MTN. They check the SIM card there was no problem with it so they told her to take it to Samsung, and the technician check the phone and said there is a problem with the phone itself it was draining the network. So I took the phone back to Ottery MTN store because I bought it there and that was on 23/03/25 I drop the phone at the store the person who help me book the phone in with box and phone but I didn’t have the charging cable with me that time. Because I didn’t think that I need to have it with because the phone was the problem not the cable. So the next day I got a msg to say device booked for collection ref:*** and that was on the 24/03/25. Then I got a msg on 27/03/25 to say MTN confirms device has been repaired and dispatched, allow 3 to 4 days for delivery back to store ref no. ***. I waited 5 days and went to Ottery MTN store to check if the phone has arrived but no phone has arrived at all then they tell me that I need to bring the charging cable for the warranty I did so, I brought the cable the next day. I did ask them why didn’t they contact me before hand to tell me that they needed the charging cable because they have my contact details but no one try to contact me at all, if I didn’t go check if my phone has arrived I wouldn’t have know that they needed my cable. I spoke to the manager a day later to ask did the phone come yet the manager said not yet and the cable was still at the store she was waiting on the phone to arrive she didn’t wanted to send the cable just so because it could get lost on its way. I ask the manager to find out where is my phone and what’s going on she could not find my phone no one knows where is the phone. I phone MTN repair number that I got and they told me that the phone was booked in under warranty but it was booked out again and booked in again as no warranty because there was no charging cable but the cable was at the store for a few days already and if they did call or msg me before the time I could’ve brought the cable to the store long time ago and then we wouldn’t have this problem so nw my wife is sitting with out a phone for a few weeks. So now we need to go the whole process through again over simple things that could’ve been avoided and we only receive the phone on the 15/04/25 back. On the day of collecting the phone, I ask to speak to the manager but could not speak to the manager because she was busy with training or something. So I ask one of the sale consultant what if the phone gives the same problem in a month or 2 can I bring the phone back to MTN even if the 6 month warranty has expired he said yes but then they will charge me for the repair. Then I explain to him how can I pay for the repair when I brought it the first time in the 6 months warranty and if it gives me the same problem after the 6 months so that will mean that the phone was not fix properly. The more I’m trying to explain to him about it the more he got a attitude thinking he knows it all telling me why do I worry about what could happen in a month or 2 and to top it of there was a private screen protector on the phone but we got the phone back with out it. I evens send a email to MTN complains management team but until today nothing has been done. I’m very disappointed the way MTN handle the situation and the **** service I got from them.
