Terrible non-service continues

On 02 May Rain delivered their second replacement router, which also does not work, like the previous one. I have requested the Bot to email the call centre, but did not receive a call back. It seems we are going down the slippery non-performance road again as we have been in the last 6 weeks. Mind you I did see a call come in from my own cell number. Would that be them? I have just spoken to the call centre and once again they are escalating. Can anyone recommend another service provider that also offers a monthly subscription and supplies the router?
