MY_MTN_Choice80Gb-24 for R299 pmX24, Remove *******ly added Data bundles

I upgraded to data MY_MTN_Choice80Gb-24 for R299 pmX24 on 29/03/2022.Total amount deducted was R2346.71 on 25/04/2022 by MTN of which R 1459,75 for data sim only. Sent countless emails refs (*** / *** / ***) and called 135 my calls keeps being dropped when trying to forward me to correct department until on 03/05/2022 a consultant (Nompumelelo) answered. She emailed me my contract and the contract package is written as " My MTNChoice_80Gb-24Month-CMBRPMPM3-CMBRPMPM1-CMBRPMPM3-CNTRP20-ITBL-MYPR10G--MYPR10G_SIM Only. She checked my account and says additional data bundles were added to my data sim number. She will log a fault to remove additional data bundles and I got refs *** / *** sent to me via SMS on 03/05/2022. On 04/05/2022 the ref ref *** / *** got closed and another sms say new subscription R315 but on MTN APP outstanding amount is R2231. I am battling to get a statement from MTN ref *** and calls to 135 keeps being dropped. I want MTN to refund me as data contract should be for R299 and not a cent more.
