Frustrated Client

I haven't been so frustrated by a service provider I'm spending my hard earned cash on. I haven't had internet connection for about three days in a row, and calling Rain Customer Care, I don't get any help, the first consultant I spoke to said I must do factory reset, ever since, my router has changed its name to something else, and still no internet, 3 more consultants that I spoke to couldn't be of any assistance, they said they've escalated the matter to Technical, but it also hasn't came back to me, and for expensive money one is paying, I shouldn't be subjected to such mediocre service.
