Vodacom pay but no service!

I have a serious compliant against Vodacom that I have been trying to resolve since last year to no success.

My vodacom contract number can only make calls but cannot receive calls or messages. I have called customer line and gone to the vodacom store but no on gets it right, I am told calls are logged, wait 48 hours and still nothing!

This frustrating becausing I am paying my instalment and for the number but not getting the service. I find this to be acceptable and I send email that this be resolved or I be refunded all the monies I have been paying for this number because it has not been in use!

Kind regards Khodani S
