Worst service experince of my life - MTN *******

Left Cell C for MTN because I thought it couldn't get any worse. I was so wrong. I signed up through iStore on a Minute100 contract which included an iPhone 6 plus 500mb data, 100 minutes talk time and I think 200 sms's, all for R499 per month. This was the ONLY contract iStore were offering from MTN at that price! My contract began on 1 April. Everything was okay for April-June, except for constant striking so no call centre. I went on holiday in June, and came back in July, put back my MTN sim card in my phone, and..NOTHING. This continued. I visited both the MTN store and the iStore on multiple occassions, and the best response I got from MTN (still no call centre) was, just wait for your next debit order and then see what happens. Resigned to the fact of poor service, this is what I did. The debit order went off (a week now with no phone), and... R100 airtime. No data, no minutes, no sms. just a \usage limit". Following this"
