Very poor customer service

I bought a phone this year July 2025, phone started acting up/failing to charger and I returned it to Telkom Illanga mall on the 21st of October 2025. Phone was returned after 2 weeks and they mentioned that the issue was fixed. I asked what was the problem and they mentioned that the phone had Software issues so they upgraded the software and since I am a Technician i asked them if the is no hardware problem and I was told that the is no hardware problem. I took the phone home and when I got home the problem started again. The phone couldn't charge eith the same error message, I called the store same time and returned the phone after a day. When I got to the store their manager Sifiso took the phone and said I should go home with the box and charger. I went home and after to weeks I received a call from the repair centre stating that I should book in the cable as well since they need it if the is charging problem. I went back to Illanga mall to hand over the cable, after a week again i received another call from the lady at the repair center stating that they finally found the problem but is intermittent but she was calling me because she hasn't received the charging cable. I did mention to her that the cable was sent over a week ago, I waited for over 2 weeks while sending emails to their repairs escalation team without getting any response. Even today I haven't received any response to the multiple emails I have sent. Few days ago after almost 2 months without a phone i am getting an sms stating that my phone has physical damage on the charging port and I should pay R849 for the port to be replaced. I just wanted to find out what caused the damage since the first time when I booked the phone in it was checked and confirmed to be okay. I feel like something happened at the repair centre that might have caused the damage if the is any damage at all. I deal with warranty and fully understand that if a device is in warranty and it's starts giving you issues you must return it to the store. What is it that Telkom repair center thinks I did to the port that they couldn't do on their site because they did mention that the port was cleaned and on my site I never even attempted to diagnose it or clean it because I trusted Samsung and I was very much disappointed in the phone because it was only 2 months old. I know that I might not even get a response to this but I am paying over R1400 to Telkom every month and I think once all this is done I will completely cancel my contracts because Telkom has very poor customer service. I can not be sending emails close to 2 months and not even once did I get a response. The only response it's the auto response emails, if you ever think of buying a phone or taking data please try other network providers because Telkom doesn't care about their customers. Is the anywhere where I can write to to escalate my issue with Telkom? I really need help. I have only paid for 4 months and left with 32 months to pay for that phone. *** and ***
