Rain, You need to do better for your clients

I am writing again because your support on the website never gets a response, and your support call line never works.

A technician came to investigate the problem, thank you, I have outlined before, (every day after 5 pm I drop to a 5Mbps line, for months now), while during the day when it's fine. After spending a few hours moving my external router around outside, (The External Router, Which was set up by a rain technician), He left saying it was a tower issue(My closest being 460 meters away), and that I would get a follow-up the next day. Well still waiting, and what's worse is now I have a permanent 5Mbps line. Coming to fix a problem, that was not the router, as that was originally set up and working by you, bar the clear throttling after 5 pm, has made matters worse. I would like this matter fixed, please.
