Had enough (of) Rain thanks!

I signed up with Rain on the 6th February, on the 13th February I received my router. Since the morning of the 27th February I have had no internet connection, I logged a call and after numerous calls, emails and eventually a review on HelloPeter you finally said I needed a new router. I received it on the 10th March and I still don't have internet connection. I tried to call your support line and the guy who I was explaining the situation to put the phone down on me. I tried several times more to log a call but you phone my Rain SIM card which doesn't have signal and I'm not wasting anymore money on airtime trying to phone you. I have had enough of Rain, so please arrange for the router to be collected and I would like some kind of refund as I only had 13 days of internet connection. Thank you.
