False information, false charges and miss leading customer

I don’t know if Vodacom is starting to be a **** or what because this is not Vodacom that I know, I am receiving sms from Vodacom saying I must make payment arrangement, I don’t know what arrangement are they talking about because I don’t have any account which is behind with them, last month they fail to debit my account and call them a day after my pay day and ask them why are they not taking mine and I was told that they don’t take money before pay day, my pay day was Sunday I call them Monday morning to make immediate payment, they say they will debit Tuesday, I was told that they will charge me 100.88 for debit order, and I say how can you charge me on my pay day and on top of that am the one who called you to remind you to take money and it was day after my pay day not even two days later, the consultant told me that she will call team leader, the team leader confirm that am not gonna be charged she will make sure that they don’t charge me, and I told her that what if they put it with my next invoice, she said No it wont happen, now I receive invoice the charges are included, after invoice now is sms after sms demanding charges, for what???
