MTN IS A PATHETIC NETWORK

I HAD 3 CONTRACTS RENEWED WITH MTN. WAS SUPPOSED TO RECEIVE 100 MINUTES PER CONTRACT PLUS 14 GIG DAY/14 GIG NIGHT. EVER SINCE, I DONT RECEIVE MY MONTHLY MINUTES. I HAVE BEEN TRYING TO RESOLVE ISSUE FOR THE LAST 3 MONTHS VIA 3 DIFFERENT MTN PLATFORMS. NON OF THE MTN SERVICE CHAMPIONS ARE WILLING TO ASSIST. HAVENT RECEIVED SUCH POOR SERVICE FROM A SERVICE PROVIDER. I AM SO FRUSTRATED AND WISH TO GET OUT OF THIS CONTRACT SO I NEVER HAVE TO DEAL WITH MTN AGAIN.
