VODACOM is absolutely useless

I had internal ***** on my account, a router and line without my knowledge (probably by a vodacome employee), which was debited off my account. I logged the ***** in November and was told it would be resolved and I would get my +-R3500 back that had been taken without my consent. While I continue to pay for the contract I did open, I am still in arrears for the ********** account and have now been cut off and who knows, possibly black listed for a ***** up from your side. Every department doesn't know what the next is up to, its one giant **** show!!! I would love to actually get the service I am paying for as well as my money back that was ******!!! They can't help me in the shop and they can't help me over the phone so what next????????
