UNNECESSARY HARRASSMENT

I had three accounts with the abovementioned company; one which got paid up end of January 2018. Now I am left with two. Payments for these accounts are effected through debit orders from my Capitec Bank Account. There is not a single month when these debit orders have not gone through. These past few days I have been inundated with calls from this company referring to me as either Mavis or Modiegi. I have on all occasions told them that that is not my name. The last call I received this morning asking me for Mavis. I politely told the lady my names. Two minutes after that call I received a call from another lady who told me that one of my accounts was in arrears. I tried to explain to her that that could not be possible because payments for my accounts are debited from my bank account and the recent payments have been effected on the 26th of January. I went on to ask her which account was she talking about exactly; to which she rep**** that her system was slow and she could not tell me exactly and that she would call me back in two minutes. needless to say that these people recently randomly debited my account for R400 on the 23rd of this month and when I called to find out the reason for this, I was told it was a system error. the reason why I am reporting these people is because I am extremely tired of the harassment that I'm getting from them; especially from the girl who rudely called me about the arrears this morning. I don't owe that company nothing. I pay my accounts through debit orders each and every month. If they have their issues mixed up, that is not my business. I am not Modiegi and I am not Mavis. They should correct their issues and leave me out of their nonsenses. I am really tired of this.
