Horrible service from MTN Retentions

Absolutely horrible service from MTN Retentions department. I upgraded my contract in December and canceled a second line the same day to lower my bill going forward due to the tough times. The consultant advised me that my bill at the end of January for the 1 remaining contract on my name would only be R299 and December would be my last bill of R948 for the 2 contracts as it was for November's invoice. In January I received my bill and shockingly it was for an amount of R1477, I called rententions and waited an hour and a half as usual only to get told my the consultant that is seems like it was an error on their side and it would be rectified, furthermore the consultant told me that I missed my payment in December and I need to speak to the accounts department, when I got through the gentleman tells me someone from Retentions moved my debit order from December to January. This ****ed me off as the whole point of canceling 1 number and upgrading/lowing the other contract was to be able to save money during these times. I've called rententions over 4 or 5 times since then and having to waiting on line over 1 hour and 3p minutes each time and all I get told is that they have logged a query. What disappointing me even more was that each time the consultants told me that can't transfer me to a supervisor and no one as called me back.

My number is ***, hoping someone at MTN is willing to work and assist me
