Bad Service

I took out 2 Cellphone contracts with Telkom in April 2021. Since last year August they stopped debiting my account. So I made manual payments. On the 25th of March 2022 I made a Eft payment. So when I contacted them they claimed they never received the money. On 11April 2022 I made another Eft payment. I keep on sending proof of payment through to the email they provided me. The last I spoke to Thandiwe on 23May 2022 at customer service she checked the system and ensured me the proof of payment is reflecting and she will send proof through to the account department. Saturday I got sms saying my account has been suspended. 25March payment was for Feb&March. April payment was for April and May. Ever since April my phone gets cut off. Then it's hardly on and then they just cut it again. I can't even load airtime on my phone when they cut it off. I'm tired of this nonsense. They are giving me a bad credit record. Can someone please help me...
