Service what service

I've been trying to sort out a credit with Vox since the beginning of November. I was told everything is resolved and low and behold I was debited an additional R1999 again. Then I get told the manager forgot to approved it.three hours on the phone to get cut of and transferred from pillar to post. I am done I want my money back by the 2nd or I'm taking legal action against Vox I've been a client for 6 plus years this is disgusting.
