No help for my Refund request, they just don't care

I have a credit of R2219,67 on my Vodacom account which i requested them to deposit on my personal account but no one is willing to help me. I logged a call of a refund to Vodacom since the 24th October 2017 and every-time i make follow up call , the consultants are telling me that they will escalate it to the relevant department but my request has not been attended to. I am a new customer to Vodacom and i regret the day i signed a contract with them. This has inconvenienced me a lot and its clear that they don't care about me and they don't take me serious as their customer.
