To ***** or not to *****

I have called Vodacom several times to investigate why the offerings on my contract for 5gig video ticket bonus never activated once since Nov 2020! The query was resolved in April by giving me a once off 5gig data but no feedback on why no activation all the other months. Vodacom quietly but steadily de*****s its clients by selling us products this way then ignoring queries until we give up.
