Complete loss of service for over 3 weeks.

I'm incredibly frustrated by the appalling service we have received. The cable was cut to our house as the contractor was trying to upgrade the cable. But was then unable to replace the new one. We have now been waiting for over 3 weeks with no end in site. We have made multiple phone calls and never get called back with an update.

Apparently this is now referred to the Area Field Management Team. Can anyone advise how they can be contacted without going through the standard terrible customer service line?

Thanks
