Terrible Customer Service

Good day, <br> IT'S BEEN ALMOST A MONTH THAT MTN DON'T RESPOND TO MY QUERY OF RIDICULOUSLY INCORRECT BILLING. THE ESCALATE IT TO ONE MANAGER TO ANOTHER AND NO SERVICE AT ALL AND NOTHING GETS DONE AT ALL. THEY VERY QUICK TO TAKE OFF INCORRECT DEBIT ORDERS BUT VERY SLOW TO SORT OUT THEIR MISTAKES. I NEED THIS SORTED OUT BEFORE THE NEXT DEBIT ORDER GOES OFF. <br> <br> THIS IS REALLY BAD SERVICE. MTN IS THE WORST SERVICE PROVIDER EVER AND WITH THE WORST SIGNAL IN SA.
