Vodacom at it again...

I have been trying to cancel a R150 data bundle that I never asked for, for months now. I was promised it will be removed when I renewed my contract, but no.. After numerous branch visits, phone calls and empty promises, over a few months I am hoping this will get some attention. The fact that my number is so old due to my being a loyal customer for close to 25 years, and some staff members cannot access the old system, is not my problem, Vodacom. Sort out this mess!!!
