********** Transaction

Yhooo am so angry at MTN service, on the 05/09/2020 i went to pay my account of R 990 as usual , at the store i was told i owe an amount of R1990 . I was shocked i enquire what happed they gave me an explanation of an recurring, i told the agent i never heard such i have been using MTN for over 6 years. So they day 05/09/2022 i paid an amount R990 as my usual instalment,I asked the agent to closed the recurring date has i did not even request, he assured me it will not happend again. The following day the closed my line i was out of service. Yesterday on the 15/09/2022 i went back to the store as i got paid i got the asked the balance they told me its R991 i paid with in few minets i receved an sma telling me i owe still an amount of R1990, i went back to the store for them to expain hows that possible the guy just said it the data again i said to them they assured me that it will not happen again and was about it no futhure explanation. I first told them that my line was out of service since the 06/09/2020 till yesterday as i paid the balance they said i have and secondly the agent assured me that he barred the serivice of the recuring data it will not happen again so i asked they how is it possible for a close line to be using that much of a date worth R1990. MTN is a big ********** company please i need help, i tried calling there customer care line no luck, i emailed them there responce was not helpfull at all.
