Fault logged with no solution

I logged a dead fixed line on 2 December. A technician came out on 3 December and determined that the fault was a broken line 2 properties away from me caused by a broken tree branch. He said he will escalate the fault to the cables department. 19 days later, 3 faults logged, many calls from technicians asking the same questions, chat agents telling me the same things over and over, I still have no fixed line and have now wasted a lot of money in mobile data and ISP costs. The last online chat agent suggested, after a 20min conversation, that I apply for a fixed line lookalike, then promptly disconnected. I need to know what my options are here.
