Vodacom bills me for a service I did not activate

My contract worth Vodacom started over 2 months ago. 1 week before they billed me the 1st month my line was disconnected every 4 hours. Claiming i have exceeded my limit. I did not have a limit. I spoke to 8 different customer consultants and was shocked how not 1 could assist me and all our them had different views of how they see me resolving it <br> Consultant 1 told me that he cannot see that my line is blocked and therefore does not know what more to do for me<br> Consultant 2 told me that my line was blocked due to limit exceeded but she too cannot see why it even says i have a limit as I'm on a top up contract<br> Consultant 3 assisted by unblocking the line but did not know why it blocked <br> then my Line was unblocked <br> 2 hours later it was blocked again <br> Consultant 4 said he does not know why it keeps blocking and swing i have exceeded my limit when he cannot see any limit as I'm on a top up contract. He advised that i will have to pay a minimum of R600. I asked if i will be refunded ad my contract is R399 per month and i was advised that my contract was still to go off that amount is just to open my line, at this stage i was outraged abd demanded to speak to the supervisor ...
