Change of banking details

This is the worst service ever. I'm just trying to change banking details. From the 5th of June 2020, however, each time I'm told via e-mail as well as telephonically that it's done and then every month the debitorder is not going through and I am just trying to understand why it's not going through? *5/6/20 - I email the debitorder form with bankstatement to change the account it should be debited. REF NR ***5 *5/6/202 Kwanele Ngobese ask the bankstatement - I have already send it, together with the form.... *09/6/20 I e-mail to ask if it's been done *12/6/20 I e-mail again to ask if it's been done *12/6/20 Venecia Maditsi ask for a copy of the ID - I immediatly send it. *16/6/20 I get a confirmation that the banking details is updated - no person's name is on this e-mail *25/6/20 - debit order does not go off *25/6/20 - I phone DSTV and speak to Jasmine, she confirmed the debitorder tried to go off, but could not, she reads back the bank account nr - it's been entered incorrectly - why do we have to send the bankstatement if it's not checked and entered correctly? *26/6/20 - I EFT an amount of R919 as this is the amount they gave me. *26/6/20 - I email the debitorder form, bankstatement and ID once again and ask for it to be corrected *26/6/20 - Happyness Shabalala confirms all is correct now. *31/7/20 - After Happyness confirmation we waited until the end of the month, but no debitorder goes off. *31/7/20 - Once again I send the debitorder form, bankstatement and ID. *31/7/20 - I also send an e-mail asking why this did not go through? *1/8/20 - Rebaone Setae replies to say again the debitorder was reversed - I ask why and that it must be corrected. *3/8/20 - I EFT an amount of R969 - because all of a sudden this is now the amount that is outstanding? NOW THE REF NR CHANGE TO - ***9 *4/8/20 - Precious Mvubu confirms that the banking details is correct and will go off on the 25th of August *4/8/20 - I ask to confirm what bank account nr is on the system - het confirms the correct one. Lerato Kwanaite confirms the correct nr. *25/8/20 - debitorder die NOT go off. *26/8/20 - I send an e-mail once again - asking what the problem is. *26/8/20 - Maseroke Kganyago phones me and tries to assist me by recapturing everything, making sure the bank nr is compliant and all is correct. *26/8/20 - The afternoon a sms comes through that the debitorder did NOT go through and that an amount of R859 must be paid. *26/8/20 I send a mail to say that again the same issue happens and that Maseroke must phone me back, as it does not help to talk to another random person. *27/8/20 - I send a e-mail again asking them to respond to my e-mail and phone. No feedback. I want to know why this debitorder does not go through. I also want to know why there's a difference in the amounts - please do NOT tell me it's for late payments as this is not possible - it's NOT my mistake that you typed the account nr incorrectly the first time. It's also NOT my mistake that you cannot sort out this debitorder? My hope is that someone will be able to contact me urgently to sort this out, someone who can actually give me answers to all my questions.
