Vodacom terrible place.

I am so so angry with Vodacom. Phone contract reached the point of upgrade, and decided that I will not upgrade and it should be put over to prepaid. Paid the cancellation fees, signed documents to confirm the cancellation and sent via email as requested by the acc dep. This all happened in Oct 2023, till now it's still getting debited and still getting recharged as contract. I feel I want my money back as all I was asked for was done from my side in Oct already.
