DATA REFILL ****!!!!

I am sick and tired of this **** called "Data refill" - I have called VODACOM on 3 occasions now, to REMOVE this ridiculous system off my phone. On one occasion, i was refunded R29 airtime, as it was confirmed that this was not in fact activated by me. Needless to say, it is still happening!! I phoned another time, and it was promised that it would be removed. IT IS STILL HAPPENING AS WE SPEAK! I called the call center again today, and the rude lady wanted to verify if i am not a ******* by asking me when / how much / what airtime / data/ bundles i have bought, and because i do not keep record in my head of dates and numbers regarding my purchases, SHE JUST DROPPED THE CALL ON ME!!! I have had it with VODACOM!! This is a way of ******** the public out of there money. I will be joining another service provider - I AM SICK OF VODACOM! when calling now, the system sent me a message that i was subscribed to two products that i have never heard of, this is really not good!!
