I need iwyze to leave me, my bank account alone. I now have to pay fnb an amount of more than R1000 banking fees because of failed debits/unpaid debits. I have accled iwyze, cancelled the policy that I had with them but no, you still have to try get money from my bank account, this morning you have tried again failed, now I received an sms"we will try debiting again on the 9th" what the heck is wrong with you iwyze. It sickening man, go to my previous call when I called in, I canceled and to my shock guess what I see now on my mails I have a new life cover contract after canceling, are you now forcing me? Flipping stop it man mxm
