DISGUSTED BY YOUR SERVICE!!!!!

I took a laptop contract with MTN for R199 a month and they debited me R239 which was not our agreement but I ignored. Few months down the line they stopped debiting me for what reason I still don't know and then handed my account over to VVM attorneys. They called me saying that I will now be dealing with them and we arranged monthly payments, which I have fully settled MY LAPTOP IS STILL LOCKED! AFTER PAYING ON THE 25TH AND HAVE ADVISED VVM AND THEY HAD CONFIRMED IT'S OPEN AND TO MAKE THINGS WORSE MY CREDIT RECORD HAS BEEN RUINED WHILE I ALWAYS HAD SUFFICIENT MONEY TO PAY MY ACCOUNTS!!!!! I WAS ACTUALLY BUILDING MY CREDIT SCORE AND RECORD!!! FOR THE FUTURE!!! I AM SO MAD AT YOU MTN AND I WILL NEVER, EVER USE YOUR SERVICES AGAIN NEITHER WILL MY FAMILY AND CLOSE FRIENDS BECAUSE I HAVE TOLD THEM ABOUT YOUR PATHETIC SERVICE! I HAVE WORKED WITH OTHER NETWORK PROVIDED WITHOUT SUCH PROBLEMS IN MY LIFE THE REASON WHY I USED YOUR SERVICES WAS BECAUSE THE LAPTOP INSTALMENTS WERE CHEAPER AT YOUR COMPANY AT THAT TIME COMPARED TO MY PREVIOUS PROVIDERS, VODACOM AND CELL C. PLEASE REOPEN MY LAPTOP AS I URGENTLY NEED TO USE IT AND CLEAR MY NAME FROM ITC OR WHEREVER YOU HAVE LISTED ME IN!!!!!!!! BECAUSE YOUR DEBIT ORDER HAS NEVER BOUNCED BACK IN MY ACCOUNT AND ENSURE EVERYTHING IS IN ORDER GOING FORWARD, YOU HAVE RINED MY CREDIT RECORD FOR NOTHING AND I AM DISGUSTED BY YOUR SERVICE!!!!!
