Poor Customer Service

I signed up with Vox last year around October, I did not pay for the monthly subscription as it is prepaid and the setup fee. The following month they sent a notice that the account was suspended and I must pay a R570 for the arrears which was 180 setup fee and the balance for my monthly credit for calls. I paid the amount and since then my account has been suspended. I made numerous attempts to get hold of them and finally when I spoke to someone in January they said I must pay another 180 for Jan and the account will be activated after a month. I paid again and up to now my account is still not active and I sent emails and no one is responding to give me an explanation as to why the account is still suspended. we are getting into another month and I will expected to make another payment for services that I have not used at all. This is poor customer service!!!!!! not happy at all.
