unprofessional and non transparency

i have an account with them, they are ripping me off, every month they overcharge me and when i query, i get nonsensical explanations all the time. I think they are into cheating people and they are not transparent.

Last month, on the 29th of May i was charged double the amount, i.e. R798 Instead of R429. Ten days after that, i.e. on the 7th, vodacom charged R485 in addition to the R798. This is unacceptable.

I am very disappointed with this dirty service, its unprofessional and disgusting.
