Rain network more down than up

I've been struggling with Rain for 2 months now. I've logged multiple tickets with rain to resolve the issue but all they tell me is to reboot or reset the router. It does not help. They ask me to do a speed test, but how can I do a speed test when I'm unable to connect to the internet? Then they send me an email to optimise my network as I'm connecting to a tower that is too far away. The instructions they give on the email does not work as there are no option on the rain website to optimise. Then they switch me to the closest tower which works for a day or two. Then I'm back to square one.

I've never missed a payment and was always happy with Rain as I even recommended Rain to my friends and work colleagues. I never had any problems or issues with Rain. But all of a sudden its like I don't even have wifi.

I've spent over R2000 in additional data that I had to buy from my mobile ISP as Rain is useless.

I hate to give bad reviews but rain gives me no other option.

I hope we can have this sorted ASAP.
