HORRIFYING EXPERIENCE

There was an issue whereby my contract had come to an end in which I was not aware of, nor was communication sent out. I then called up 135 and there were really unhelpful, but after a week or so I eventually got my refund. Prior to the refund where I initially called to see how I have been charged for than 2 x my actual bill, I had asked for my Device Contract number to be barred in which they barred my DATA contract as well. I had been trying to upgrade before the billing cycle which was the 12th and I kept getting told this cannot happen as there is a bar on both numbers. I went to the MTN Direct Store at the Pavillion and was assisted by a gentlemen named Lungile or Luyanda and further to that a Manager Lindy advised she will call me after investigation. It's over 10 days and still no help. Went back to the store on the 30th. No help and I am debited again extra due to MTNs mess up! I am now put in a bad financial situation
