Multichoice not pay my refund

I'm paying my Multichoice Dstv account with Fnb App, 13 December 2019 when I was paying it keep on saying I must try later, I did that 3 times, to my suprise the following day R3000 was out of my account instead of R1000. I reported to Multichoice and they told me to send ID and bank statement, I did that and called them, they promised to refund the money within 7 days, every call I make to do enquiries they told me send the documents again again n again, after the response changed to "you will get the money tomorrow". Every time it's an excuse after an excuse and also I was told the finance they are approving the transaction. I'm tired of them, they don't care about their clients and the emotions they put us through. After getting my money I'm deactivating all my accounts
