Worst service

WORST service ever. I tried calling needing assistance with resetting My fibre password but because I did not have enough airtime, I decide to seek assistance from vodacom Facebook page as always n usual get assistance when I get there. The person that was assistance doesn't seem interested, instead they telling me I should call instead, My password changed without me changing it, it kicked everyone out n saying access denied. Am paying every month but still getting a message saying access denied. Why am I paying if I'll be getting such.
