Extremely poor service from Rain

If I could give no stars I would have. I can't remember the last time I had such poor service from a company!!!

I signed up for 5G from Rain. I received the router a week ago and guess what? I still don't have internet. Also keep in mind I have already paid R700 in advance. There seems to be no signal here, even though when you "check signal" on their website we are in the signal area. I have been trying to get in touch with them, but the answering service tells you to e-mail. I have sent more than 20 emails and they keep emailing the user manual over and over (which doesn't help). Yesterday I decided to cancell because of their no care attitude and very very poor after sales service. I sent them an email asking how I can go about canceling. It is now 24 hours later and still no reply. It would be wonderfull if I could actually talk to a Rain consultant, but even after I emailed a few times asking for someone to call me so I can explain the problem, the still keep sending me the user manual. I can't understand in these economic times companies can have this don't care attitude!
