*********** MTN staff

I have made countless calls to MTN 808 since beginning of April requesting them to change my debit order date to last day of the month. I don't understand where the difficulty is, at some point one of their call centre agents asked that I email them to remind them to change the date, of which I did but still nothing was done. I'm incurring unnecessary UNPAID charges in my bank account, this is ruining my credit record. I'm livid by their level of incompetence over such a small request. I understand they were on strike, but my query's been open before their strike begun.
