VODACOM ****MED ME

I purchased Fibre at vodacom last year August and in december I noticed I was being overcharged as not all my debit orders were going through and I know this because they should've all went through as I put in a specific money for all of them . I called the vodacom company in January this year about this matter and they had said to be trying to refund and fix the issue but nothing changed I had not received any money. I wanted to apply for a second bond but I had seen that vodacom had listed me for being a late payer and I went to vodacom physically in Vangate Mall and they told me that I needed to pay R5186 to be up to date with my billing in vodacom and I paid this amount even though vodacom had been double charging me since August 2022. I've been calling the vodacom company constantly about this issue and they had said the same thing which was they were trying to refund me and remove the listing. It is now March and there is no change. I even tried to cancel my account this is the reference number: SR***
