Vodacom *****s ur money.

I have made a payment to Vodacom in august/Sept. I put a reference 1 instead of an I. Now my payment is just missing. I have done everything to sort the payment out, in store online email and and and.... My phone is now cut off for "non payment". I get told by the customer service that it's my fault and they can't help me. My money is in Vodacom bank account. My bank cannot reverse the payment because it's to "old". WHAT MUST I DO??
