Over R5400 ******

In November I got a call from MTN offering to increase my data to 20gb at the same price I was already paying. I opted to take the offer after the sales person assured me that there would be no addtional charges. When my January debit was deducted from my account, there was an additonal R5412 charge for a migration fee. I lodged a compIaint in the contact form on the website and called MTN on the 4th of January. I spoke to Sandile Makwa**** who supp**** me with the bill in question. He then told me I have to speak to the retentions dept. Retentions dept took more than 2 hours to answer call at which point I had to go. The agent said he would call me back but did not. I had to go through the whole process waiting almost 2 hours again. When I was eventualy connected, I was told that billing had to deal with the issue. Called customer service once again and was told they had to escalate my issue. Still waiting on a response.
