Bad after service at Cell C George branch

After service is horrible after buying a special from them at George branch York Street a WiFi router that comes with data every month for a year. The first month was a battle to activate the simcard and after shouting at them I received data. Second month no data. After a battle I received data and we are in month 4 still no data for 2 months. I phoned and they send Abraham to come see me and with a promise to assist and come back to me the next day I am still waiting for him and still no data.
