Worse Service Provider Ever!

If I could give 0 stars I would! I canceled my contract with Telkom in April of 2020, asked the person that assisted me if everything (including the insurance) will be canceled to which they rep**** yes. May went by and no deduction, June came and they deducted money off my account with no invoice or proof of what it was, so I reversed the debit order because I thought it was a mistake. They got back to me in June and told me it was for my insurance and told me I need to phone Finrite to cancel. I tried phoning and when I EVENTUALLY got someone to answer, they told me to send an email. I sent the email and for 2 weeks no one got back to me, so I tried phoning again for the rest of June almost every day. So beginning August I FINALLY got some assistance and my insurance was canceled. Now they not only debited the full amount of my insurance but more than double what I used to pay. Today I tried phoning Telkom's accounts department and they informed me that the extra was for a rejection fee. I am now fuming because the team leader still hasn't gotten back to me and I still have no idea why the money was debited! I am sick of Telkom using my bank account as their personal ATM! They have done this to me not only once but 3 times in the past, for as long as I was with Telkom I have never received a statement and/or invoice and just no communication from their side! When I phone I'm on hold for 20 minutes or longer and when I put down the phone my problem is still not resolved! I always have to get hold of them when there is a billing ussue and it just seems like nobody there knows what's going on. I will never EVER refer ANYBODY to Telkom because every form of service of theirs is just terrible! They deduct money off your account with no explanation or proof of what it was for and just ko communication! Highly highly disgusted!!!
