Bad service, theft and ********** company!!!!! #MTN SUPERSONIC!!!!

Supersonic should sort out this billing error, bunch of ********, I don't owe them money at all, I'm paying vumatel R394 each month and online supersonic statement says I owe R7600 which is incorrect they keep saying it was an error on their side, each consultant I speak to tells me the same thing its incorrectly billed as I'm not supposed to be billed if I'm with vumatel, but since April last year 2021 ims truggling with this company to sort this out, nothing has been done, numerous tickets created, no managers available to speak to not can they place me through to their billing department which I don't even think exists. Hours on the line just to hear apollogies which doesn't help as my itc credit score is ****ed up due to this and nothing is being done by the company to spirt it out, they using mtn's brand but yet if I go into mtn store they tell my they have nothing to do with supersonic, ***???
