Extremely bad

I have been using Mtn service providers for years now. Account payments on time and upgrades dobe each 2 year. For the Month of Feb on 27th my bill was R 2420. Payment was done immediately. On the 3rd March Mtn has deducted another R 2420 from my banking details which I liaded to make a once off payment. And surprise on the 7th of March the normal debit order went off from my husband's bank account. A SHOCKING R 7260 have been taken by mtn though I only had to pay R 2420.

I phoned in numerous times with the same procedure done to ask me to email the statements with proof. Have done so 3 times. No feedback or a escalating reference. Went in to the branch and exactly the same feedback! 2 Weeks later. No reference number. No indication of a correction to tge payment. Nothing. Very dissatisfied customer once we resolve this issue I will most definitely move services providers.
