Poor service

I have my line disconecceted once and again with Vodacom. I do not have any arrears. Amount owing is for end if September 2020. Please can vodacom explain whats going on?? Its a nightmare to contact customer services for such a huge company. This problem happens everymonth to me. I would like to ask vodacom if they are going to resolve this issue or must we kindly move to other cellular companies ? The last consultant contacted me from vodacom tried to blame shift me.
