Bad service

I got double billed this month. I tried phoning customer care but there is no option to speak to a mtn champion if you press 0 it tells you invalid option. I finally got through to a consultant by using the upgrade prompt to be transferred but no i get cut off this happend 3 times so now i am on the verge to stop your debit order good luck getting a hold of me let's see how you like it or get someone competant to phone me asap.
