Blue label Telecommunications - Refund

I had a cellphone Contract with Blue label telecommunications about two years ago. The deductions went very well until this year, so what actually happened they continued to deduct whilst the agreement period is over. I phoned them laying a complaint about the deductions, they resolved it. As much as they stopped the deductions,they are not refunding me the extra cash they deducted from my account it's been four months now ,and I'm phoning them every week ,two to 3 times a week but nothing is happening. They required a bank statement more than two times I did sent them that, but still nothing is happening,no response, no feed back,no nothing.truly speaking their consultants keep on telling me the same thing. I'm the one who is doing the follow up. I've been trying but now I give up. Please assist.

They haven't phoned me, I still use my resources to contact them, instead they keep on asking the same documents I sent them more than 5 times

Truly speaking, that company doesn't care about their customers. They only wanted to get my money and carry on with the business now I'm starting to wonder if that's what they do to other people. Since may I've been phoning them regarding my complaint. They haven't refunded me my money or giving me any feedback.
