MTN still can't be bothered

Good day Zanele Please note that last months invoices have not been received, nor have those for the preceding six months. I don't know where it is that you think these are being sent, but it certainly isn't to my email address (which has remained unchanged for the last 10 years). Also to note that you called when I was on another call, did not bother to leave a message, and called from a number that say it "the number you have dialed does not exist" when one tries to return the call. This is the very epitome of unfriendly and inaccessible behavior toward your customers. You've had six months to resolve this and have in that time done absolutely nothing. Kindly resolve the problem before then end of this week, or this matter will be escalated to ICASA
