3 weeks!

3 weeks! 3 weeks that we have been trying to log a complaint and we still have the same issues. We have intermittent connectivity ( often down at night and sometimes in the day - which is terrible for business). Every time we phone/email we are asked to check our router, which we explain we have done but to no avail, we are then promised that a team will be sent out to investigate. 3 weeks later we are still waiting. Unacceptable....but you will still take my money every month? I am shocked by your service! I just tried calling again....was on hold for 8 minutes and then the call cut...twice! We have emailed 5 times. What is it going to take to get you guys to do something?
