*********** Call Centre agants Play ping pong with me

I had a contract with Vodacom & contract ended long time ago, maybe it's even 2 or 3 years now, The contract was not renewed and I asked them to convert the number to prepaid, they refuse to do so, so every now and then the line stops the caller identity & all calls appear as unknown then I have to call them to fix and we do this every year or even twice a year.

Just today, I called the contact cancelation department they told me the number is not on contract and everything is okay i must call the customer care, the customer care say the number is a contract i must call contract cancellation. They playing ping pong with me & my valuable time. they clearly don't know how to solve this, so this is my last resort before I cancel Vodacom completely.

Please make the number prepaid once and for all, and delete all contract information from your system, I will never ever take up a contract with Vodacom.

Also do not tell me to check settings on my phone as no settings were changed on my side and we have been doing this where Vodacom fixes it and it goes back again and i have to call again & again. It has to eventually stop and i believe making the number prepaid would be the solution.
