Cellular network

<p>Hi my cellular network has been off for more than 3 weeks I've paid my monthly fee for my contract phone at vodacom but,according to them there's no payment.I've even send proof to them witches state's that the payment was successful but no one can help me.Every time I spoke to a consultant they had different stories no one can solve this problem and it's costing me dearly at work..</p>
