Contractual agreement dishonoured by Vodacom!

Vodacom deactivated one of my prepaid SIM, sold the number to someone else, and failed to give me notice of such in advance. It is stated in Vodacom’s prepaid sim Ts & Cs that they are to give notice of deletion. Such notice was reasonably possible for them to do BUT they did not. I reported their breach of contract but they did not take responsibility nor did they offer a remedy. I hold many accounts with Vodacom and I honour my contracts with them. I want this issue rectified immediately - urgently contact me.
