Incorrect Billing

I have had a contract with MTN for the past 3 years and their service has been very poor, Their consultants are very rude and dismiss any query you bring forward. I upgraded my contract from a Blackberry to a Samsung S4 mini in 2014 May and was told that my contract is a top up and monthly subscription will be R199.00,since October/November 2014 MTN has been debiting me between R350-R400 and when I enquire about the reason for my billing fluctuating I am give 100 different reasons by very rude consultants that respond to my call. The last call I made to MTN after numerous complaints I spoke to the Supervisor named Tutu Mabiza who advised that this matter will be resolved in 7 working days and my money will be refunded to me,however this is the fifth call logged and I have been told that it will be resolved in 7 days but nothing has been done about this matter.<br> <br> I need to know how MTN trains their staff as well as do they not record their calls to hear the communication with customers, this is very unprofessional and ********* and I want my MONEY BACK!!!!<br> <br> This is the reference number that was given to me by MTN:***......
