Vodacom Does NOT Respond to Service Requests Timeously

I have been trying for three and a half weeks to get Vodacom's Service Department to come adjust our Vodacom booster. We run a business from home and are losing sales due to Vodacom's 'couldn't care less' attitude. If I could, I would rate them MINUS 5 Stars. We pay on time every month - RED packages at that! Vodacom is very quick to disconnect your service if your payment is slightly late, but will take two months to respond to a service request. This is not the first time we have experienced this. I am constantly told it will be attended to, but no luck. I am told it is 'in progress' ??? I cannot speak to a supervisor - they are in a meeting...... They do not call back - what now, Vodacom?
