Over charge and incompetence

MTN is the most *********** supplier in South Africa. <br> I have had a problem with my contract from the day I got it (ie 01/05/2015) I took the contract for<br> R199.00 ( includes BIS 50 min and 100 sms) but MTN charges me R129.00. Firstly they took 17 days to do a SIM Swop . Whenever I queried I was told MTN is stricking. This is the worst telecommunication company in South Africa. When I enquired about the discrepany in charge I was told that there was an increase in May 2015.<br> It amazing that MTN was on strike then so how did they Increase and when did they notify their customers .<br> According to MTN catalogur for the month of May the contract was advertised for R199 ending 31/05/2015<br> This is unacceptable.
