MTN 0 star rating!!

If it were possible to give a rating of -5 stars I would have done so! MTN in error billed me for a rediculous amount of: 23/11/2020 E******8 Invoice R2 414.54 23/11/2020 E******8 Invoice R2 414.54 23/11/2020 E******8 Invoice R2 414.54 on the same day for no reason!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Best is this is going to be deducted from account!!!!!!!!!!!!!!!!! If I did not saw this and queried they would have ****** my money. Logged reference REF: *** but it will take 72 hours to resolve, unreal!
