BAD SERVICE FROM CELL C

I AM BATTLEING NOW FOR OVER 12 MONTHS TO SORT OUT A PROBLEM WITH CELL C REGARDING ROAMING ON MY ACCOUNT THAT THEY CAN NOT SORT OUT. I PAID THE AMOUNT OF R14000.00 JUST TO GET PEACE AND STOP ALL THE AMOUING PHIONE CALLS. I ASK TO CANCELL MY CONTRACT AND CRDIT M,Y ACCOUNT WITH AUGUST AS MY CONTRACT CAME TO END AT THE END OF MJULY 2019. I DID NOT RECEIVE ANY DATE OR AIRTIME FOR THE LAST 6 TO 8 MONTHS DUE TO MY ACCOUNT BEEN BLOCKED, BUT CELL C DOES NOT CARE TO SORT OUT PROBLEMS AND JUST LKET THEIR PEOPLE WITH ATTUDITE PHONE YOU. THERE IS NO CUSTOMER SERVICE AND THEY DON'T WANT TO CANCELL MY CONTRACT DUE TO THE OUTSTANDING AMOUNT BUT THE CONTRACT CME TO AND END AND I STUILL AWAIT THE CREDIT FOR AUGUST AND NOW SEPTEMBER ASWELL AND A RECON I HAVE REQUESTED. BUT QEUST WHAT NO FEEDBACK AGAIN. I RATE CELL C AS THE WORST NETWORK FOR CELL COMMUNICATIONS IN SOUTH AFRICA.
