Poor poor poor poor poor customer service from telkom

I contacted Telkom on the 03June 2020 spoke to Phumlani indicating that I have changed my bank and that they must deduct from my new bank account. Just to find out in mid July 2020 that they never deducted I contacted again on 30July making sure that it would be going off on my new bank account I gave on the 3rd of June 2020 I then spoke to Phumla that indicated it will go off of which it again did not go off, I then contacted again on the 03 August I spoke to Mbatha as my wifi router did not work then I was assured that it did not show yet but debit order went off on 31st July 2020. I again phoned on the 4th and spoke to Rethabile after I received an invoice that I must pay a rejection fee of which I couldn't understand and was told that the accounts department was not notify but I asked what does that have to do with me as I contacted you three weeks in advance before the debit order date. I sent emails and nothing till thus far has been done I was told that it would be removed as I cannot be held liable for their mistake as I informed them in advance. I phoned again on the 6th of August I then spoke to Babalo at 08:53 I explained my concern and was told that the payment is reflecting and he spoke to the manager and my account will be open after an hour I waited and it's 6hours later and it's still not working I even got a dropped call when I started explaining my concern a person called Neo female didn't listen instead dropped the call after 40 min of holding wanting to be assisted. I cannot do my work as I'm having this problem that Telkom is refusing to assist me with. When I contact the 081 180 number again at 13:57 6th August 2020 I spoke to a Thando lady after complaining she told me phone back as our systems are offline she cannot assist!
