Telkom debits incorrectly for the last 5 months. One month later after I escalated account dispute and I am still waiting

Worst provider when it comes to accounts. I took 2 cellphone contacts with Telkom mobile, my contracts were R469 pm each. Telkom has been debiting me irregular amounts, without sending me invoices for the amounts they plan to debit. I found they had a different email address on their records, statements were not coming to me. It's a mission to get a contact number for Telkom accounts. I finally got a hold of an agent, the query is a month old now. It was an 'escalation' with a case number and still no feedback. I call in daily, I get placed on hold for atleast 20 min for the agent to read through my case. they still give me a generic response, to wait until they resolve query. My invoice says one amount, yet I get debited a higher amount. It gets better, even after informing them on their error. I get daily sms from Telkom informing me that my account is unpaid. I have take a look at my invoice today using the Telkom app, it now says I will be debited R2800 (3 x my premium), yet they debited me R1500 on the 25th. Telkom is a complete mess, I will never use them again!

Oh and the signal is very bad too.
