Wifi connection

I am a rain customer and don't miss any payments. I've been having a problem with my router since from Saturday morning I've been raising my query with rain since then. I don't get any help 4days I don't have any connection and I use this wifi for work and home purpose. I know at the end of the month they'll want their full pay buy for days now I don't use it. When I call they tell me to wait for their call I haven't had a call back since. I'm really not happy not sure if I should just change to another network where I can get help when I need it.
