Terrible service from Rain

My issues with Rain has been for a month. Started with consistently poor connectivity and robot assistance from the call centre, like reboot your router. After a number of weeks I insisted on a new router, which they then all of a sudden said I should have had, since mine is outdated. It took a week for the router to arrive due to them using CCD Couriers which are also useless. Upon arrival we established I also need a new SIM, this took another week to arrive. Nothing is working. Another week has passed. Daily calls to the call centre, daily promises they will escalate, they can see the router has not been activated. Then placing me on hold for long periods only to come back and say they will escalate. Nothing happens. Today's call - the agent says its not her job, it needs to go to another department, she will escalate. I am beyond frustrated and angry
