If you want the worst possible service delivery, go with vodacom.

Taking 27 days to install fibre with sending out a technician & delivering a router. Each time ive escalated they've basically told me to **** off and that they cant give me a straight answer on an eta. They only seem to care about signing you up and taking your money for the next two years, the service afterwards seems to be them spitting in your face and expecting a thank you in return.

Apologies with no actual resolution is not a solution to poor management and false promises.
