No response on a simple minor issue

since Monday the 14th of September I have been trying to get hold of a formal statement for the outstanding amount that I need to pay MTN. I contacted one of the credit controllers who sent me a typed email of the amount of which the financial institution who will be making the payment rejected because it is not a formal letter/statement. On the 16th of September the credit controllers were on training for the whole day and there was no one to assist since everyone in that department was doing training. Today the legal department has an issue with the phone lines which MTN has been trying to resolve since this morning and i cannot get through to anyone, all the alternative numbers do not work. I have 7/8 reference numbers for my complaint. about 3 customer care personnel has sent emails on my behalf to the legal department and stipulated how urgent my matter is I haven't received anything.<br> I just need a formal statement with a MTN letter head so I can make the payment immediately.
