Line fault on router, no one to contact

[#1]

Our router is displaying the symbol for a line fault and obviously, at the moment we cannot contact anyone to help us we've tried resetting the router, testing the master socket but nothing. 

Anyone have any suggestions other than climbing up a telephone pole myself, we're working from home so we need a connection!

Double posting causes confusion and does not help.

As a stopgap have you considered using mobile data? Giffgaff are currently offering 80GB that lasts up to a month on a monthly contract for £20. They use the O2 network so works on an unlocked or O2 phones. Giffgaff allow tethering, assuming that your phone allows it. Alternatively a Huawei E5577 MiFi unit does the job for you pretty effectively.
