Vodacom Fibre

I signed up with Vodacom and had the installation done on the 11th January. I have been phoning every day for over a week as I still don't have internet connection The modem is working and I can access the wi-fi on the modem but no internet access. Every time I phone I am told it will be escalated and then nothing. I am seriously thinking of just cancelling the contract and having the equipment removed and look for a provider that can provide the service they say they will. I feel sorry for all the other people who will have to put up with this very poor service from Vodacom. They can't even contact me to tell me what is happening
