Telkom's poor customer service

Have been advised by Telkom that my Account is behind due to missed debit order that takes place every 25th day of the month. The reason for this being i have switched my banking details from another bank account to another. my biggest concern was that when my banker and i communicated with other accounts, Telkom never answers their customer care line. I struggled till it was my pay day on the 25th of August. Now that they noticed a mjssed payment the called me a day after to make a manual payment and told me they can not redebit when i asked them since there was lack of communication, so i can redeposit the monthly premium of R500+. It was unfoetunate for me to be told that Telkom never redebits after it has missed the funds, however i was told that i'm already in arrears of R200+ on the 26th of August, meaning i was now owing an amount of R700+. Then i have requested for an electronic option to pay and in the meantime asked if i could now get assisted with switching of banking details. I was told that it could not be done at that time till my manual payment reflects of their account. Mind you the recommended i must call uai g the customer service line again. Where i battled. Then i googled and got an e-mail address and communicated bank switching via e mail and someone responded early in September, even asked me for proof of my new banking details which i did. Now come the 25th September, the same happened, and i started receiving automated calls, calls, sms, and e-mail, however with different ballances. i was threatened that if ai dont make payments as soon as possible, my account will be suspend with penalty fee.Mind you i hve been charged with another R200+. Simply because Telkom went to debit again from my previous account and obviously there wont be any suffient funds there. Then on my e-mail statement it was stated i owe R1 400+ which is double the amount i shld be pating for September month. I continued reaching out to Telkom customer services, and this time got lucky and spoke to one lady consultant who said on her system i owe R700+ and she said thir statement presented via email might be behind and not updating. I was even advised that my account is no longer with them i' have been handed over to their debt collect. Im worried now Telkom is ruining my credit record, for i have never nossed any payment with them till this poor service and miscommuncation. They are treating me as if im the most terrible payer and making my life more difficult by not actioning whereas ive been requesting for switching of banking details for the past 2 monts. I was also advised by the consultant that normally the process takes 30 day to be effective, though she told me they will be debiting from my new bank account, i still fear that more charges will incur and Telkom is puahing me so i end up not affirding my account as ler contract i have with them and mostly my credit record. They once didt it one December in 2021,where i got debited and amount if R1 000+which was beyond constract and when i enquire the said its because i have used the Telkom app and told them uajng the Telkom app does not have to change my contract and we had a long urguement and i ended up paying the amount. It hapoened again when i received my upgrade Phone. It was closed for many days and i struggled for them to open the line for me, while im getting debited, and when i requested for the complaint no. none of tge consultants wanted to assist me. I just dont understand why Telkom reponds to sales call center, while customer care never responds. sometimes customer care will just drop your call while your are still holding. Is it because they know we are ready in contractual basis with them amd now they dont care, amd only care for those still applying to be in contracts with them. something is just not right out there
