NO RESPONSE FROM MTN

On the 3rd of October 2015 MTN deducted some money from my bank account and again on the 3rd of November for a larger amount YET I HAVE NO DEALINGS OR ANY CONTRACTS WITH MTN. I've approached my bank on both occasions and the money was returned and I was responsible for bank charges.I managed to get hold of a MTN consultant after many occasions of trying and been put on hold,calls been dropped and been transferred from pillar to post.I eventually get to speak to the consultant and got all paperwork and emailed it to him to get the complaint lodged and get the problem resolved.Up until today I had no response from MTN. Getting a little frustrated now.
