call centre not answering and more

I cant believe how horrible the service at MTN has become. I have been a customer for a long time and I will now cancell my contract and go some where else. You cannot get through to the call centre, the call drops the whole time, i have tried 27 times today alone to try and get through. <br> The other issue is, i walked into an mtn store and asked if I can upgrade, there she showed me that I could have had an upgrade in January and my contract was eligible to be cancelled in May. I sent numerous sms's UPGRADE to what ever number, checked online and was allways ignored or said not eligible. I WAS ALSO NOT INFORMED THAT MY MONTHLY PAYMENTS WOULD GO UP BY 10 RAND IN ANY WAY BUT ONLY TO RECEIVE A THRETENING SMS THAT I MIGHT BE CUT OFF IF I DONT PAY. THIS MONTH MY OUTSTANDING AMOUNT IS R225 FOR SOME REASON, ALSO NO NOTIFICATION<br> <br> YOU WILL CANCELL MY CONTRACT IMMEDIATELY OR I WILL FIND OUT WHAT LEGAL STEPS TO TAKE WITH A LYING AND CHEATING CELLPHONE SERVICE PROVIDER. THIS WILL GO ALL OVER SOCIAL MEDIA AND AS MANY NEWS PAPERS AS I CAN FIND
