MTN POOR NETWORK SERVICE

MTN RECEPTION IN THREE RIVERS HAS BEEN VERY POOR TO NON EXISTING AND GOING DOWN-HILL AS WE SPEAK . I CAN NOT EVEN PHONE THE CALL CENTER FROM MY CELL PHONE. PLEASE LOOK INTO THIS PROBLEM, I HAVE TWO CONTRACTS AND RUN A BUSINESS, LOAD SHEDDING AND A NON EXISTING CELL PHONE NETWORK IT JUST TO MUCH!
