SO IRRITATED AND CAN CRY

I AM SO TIRED OF THIS, I JUST RECEIVED A STATEMENT THAT I OWE MTN R1900.00. I MADE PAYMENT OF R1300.00 LAST WEEK AND MY SERVICE IS STILL DOWN. MTN IS PATHETIC AS NO ONE PROPERLY HELPS YOU TO FIX YOUR CONNECTION PROBLEMS. IT IS NOT A COVERAGE PROBLEM, BECAUSE THEN MTN DOESN'T HAVE COVERAGE AT EVERY SECOND BLOCK IN RANDBURG. MTN I AM SO VERY DISAPPOINTED AS IVE BEEN WITH YOU GUYS SINCE 2012. I WILL DEFINETELY BE CANCELLING MY CONTRACT WHEN I GET TO UPGRADE.
