Vodacom will not cancel my month to month contracts to prepaid

What a bunch of *********** people! I have been requesting Vodacom since November to cancel 3 of my 4 contracts which have expired (They are now on a month to month contract) and after fighting for months they promised that it would be cancelled end of Jan. We finally get to the end of Jan and they only cancel one. After 15 years I will now look for another service provider. Time to escalate to ICASA.
