bad service

I have logged a call on the 11th of September concerning no Internet and was given a reference number to follow-up with regards to no access to the Internet. Till this day we don't have Internet and payment was made for the month of September someone called and promised to solve this issue on 16th of September and I still have no internet and on Friday the 19th September 2 guys came I'm not sure what they did but was told we should wait for the green light to stop flashing and it will start working but today is Sunday the 21st and I still don't have internet so from the 11 to 21 which is 10days my question is what is going to happen seeing I haven't had WiFi in 10days.
