Rain wifi

I am so frustrated. We never had problems with rain until they offered us the upgrade router. They said we just have to phone to cancel the old router. The cancelation department is non exist, because we have been trying for months to reach them. Only to be told that they will escalated the problem.

So we are being charged for 2 routers for the last 4 months. Every month we have to phone them. To only charge us for 1 router and then we can never cancel the damn first router. So we are sitting without wifi... Every month I have to make payment in full but we go without internet for a couple of days.

Can someone just please sort out this cancelation so I can get my wifi on. Just do your jobs please!!
