Disappointing service

Good day, I am so upset and disappointed with the service I received from Telkom. I've been a customer for a while and have multiple contacts, so does my husband. My current contract is up for renewal and I seriously considering moving. On the 24.12.2019 an attempted deduction was made on my bank account for the monthly premium, there wasn't funds in the account, so it bounced. Funds were available from the 25.12.2019. The premium went off on the 02.01.2020 R599.62. I started receiving sms's indicating I'm in arrears, I was handed over!!! I called the call center, I can't recall who I spoke to, I was on the call for 30mins, I maybe spoke to the consultant for 10 minutes or so, but was on hold the rest of the time. I ended up sending my bank statement to the consultant as she couldn't see the payment. I did not receive any feedback, the interaction was frustrating and useless. I called again, spoke to someone else, she seemed to know what was going on and indicated it would take a week or two to reflect, she logged it against my account. I'm still receiving sms's, it wasn't resolved, I called yesterday, spoke to Millicent, she was rude and I was not willing to talk to her further. I asked to speak to the TL, after a while, she came back and advised the TL is busy with a complaint and will get back to me. I'm still waiting for Thando Dlamini to contact me, I'm still waiting for the problem to be resolved. This is truly rediculous.
