Charges kept being added on bill

Since 31 May 2015, I got billed wrongly with \content charges\". The first time I made contact with MTN the \"content charges\" was on the 31st of May 2015, when I visited their local office in Beaufort West and useless to say without any success.<br> <br> Thereafter I visited the local office several times, send several emails and phoned the 808 number several times. MTN promised to remove the \"content charges\" if there were any, but no prevail. <br> <br> I dialled *141*5# today and there is no \"content charges\".<br> <br> I am in possession of my January 2016 account and still they billed me for it. I decided in August 2015 to cancel my debit order, but still went on to pay the monthly contractual amount, but after a short while MTN switched of my phone. I had to pay all charges before they switched on my phone again.<br> <br> I am very FEDUP with MTN and hope you can resolve the issue on my behalf.<br> <br> Reference nr: A***<br> <br> Thank you<br> <br> Hein de Ridder"
