bad service

Vodacom cut off my line cause of non payment. They expect me to pa the account without geting a statement to know how much is due. They gave me the amount over the phone and I paid the account. They said they'd send me the statement to date I have not received anything. The have activated my phones but not my 3g and wifi. I phone them everyday and they keep on saying that the line is active but it is not I have absolutely no access to the Internet and email via my pc and this is where I do my work from. This is bad service please can someone assist?
