MTN REALLY BAD SERVICE

I HAVE 2 CONTRACTS WITH MTN, ONE EXPIRED END OF NOVEMBER 2014 AND THE OTHER ONE EXPIRED IN FEBRUARY 2015. I HAVE BEEN CALLING MTN SERVICE LINE 808 SINCE DECEMBER TO TRY AND CANCEL THESE CONTRACTS BUT TO THIS DAY I AM STILL BEING DEBITED FOR THESE EXPIRED CONTRACTS WHICH I NO LONGER WANT. WHEN I CALL 808 I WILL EITHER HOLD FOR AN OPERATOR UNTILL I GET CUT OFF, OR WHEN I EVENTUALLY TALK TO A CONSULTANT I GET TOLD THAT SOMEONE FROM CANCELLATIONS WILL CALL ME, I HANE BEEN WAITING FOR 3 MONTHS FOR THAT CALL. I RESORTED TO EMAILING THEIR CUSTOMER SUPPORT BUT I AM STILL NOT GETTING ANY ASSISTANCE IN THE MATTER. I WENT TO THE MTN STORE AT POLOKWANE MALL OF THE NORTH AND THEY TOLD ME THAT THEY CANT HELP ME, I HAVE TO CALL THE SAME PEOPLE THAT HAVE BEEN OF NO HELP TO ME. I AM VERY UPSET AND STRESSED OUT AND DISAPOINTED WITH THIS KIND OF BAD SERVICE. THE REFERENCE NUMBER FOR ONE OF THE CALLS I MADE EARLIER THIS YEAR IS ***. I REALLY HOPE THAT SOMEONE WILL BE ABLE TO RESOLVE THIS MATTER FOR ME AS I WANT NOTHING MORE TO DO WITH MTN. THE TWO CONTRACTS IM REFERRING TO ARE UNDER ACCOUNT NUMBER A***
