Vodacom has caused me nothing but stress. Stress stress

We have an account with Vodacom from 26 July 2020.our standard top up subscription is 299.all of a sudden this year our account has been changed or migrated as they say every week we have to pay thousands of rands.they even took our account to collections.I have been calling them every week.I was told on the 2nd of June that my account will be credited however today my line has been suspended I call again and they told me that the query was sent to wrong department and is still open.No one is willing to help the situation at Vodacom instead Lebo one of their consultant told me if Im not going to speak to them nicely she will hang up which she did..I'm now treated like a fool.like a stupid..I have spoken to them on Facebook even that didn't help..I'm tired.Im frustrated.I don't know what to do anymore.nothing has been done instead the money keeps going up and up none stop
