Rain bad support

I have joined Rain at the end of October. Ever since I had this service I hardly had a full day of internet access. Recently Rain exchanged my indoor router with an outdoor router, when the service is online it works well, but that is minimum. Every morning the sevice is offline and halfway thru the day it will come back for short periods of time. I was told numeroud excuses why.....the problem is that good money were paid for this service but I hardly had the use of it. I wonder how Rain is going to handle this issue, because how many excuses can they dish up further. Their support line can't bereached and when you contact them thru a ticket from the mobile app, it takes them days to respond. Am I the only one that are treated like this......
