Vodacom customer service just useless

<p>I once had a contract with vodacom many many moons ago, even before Nene was finance minister, and Vodacom was still blue. The contract ran out, I closed it, and reverted to prepaid, better that way. I have been using it as prepaid since then, until now. Now I want to do a sim swap and put it into a different device, I cannot. The sim card is still the blue one, has been cut many times to adapt to new sim sizes, ON PREPAID, and cannot fit into an adapter. Hence the need to buy a new card and do a sim swap. Last night vodacom claimed I answered their questions wrongly, despite me telling them I haven't used it in three months. I have switched the old phone back on to get call records, now they tell me that my number is on contract, it is not prepaid. WHAAAT???? And they send me from pillar to post without any joy. How can service be that bad, and useless? Are you kidding me? How did my number become contract all of a sudden? Without my knowledge?</p>
