RAIN internet- Deceiving?

I have been trying to get into contact with Rain all week, (5days now) and still had no response. I purchased their 5G router to use for working from home and to be able to have clear, non interrupted video streaming for most of my work. I was assured there would be great signal, no interruptions and no delays with there 200mgps R999 option. I connected my router on wednesday after hours of trying to even get a connection, they assured me and it states on the website that where I live is in a 5G zone but yet finding that signal is almost impossible. I have had the worst signal, delay in videos, buffering constantly. I initially asked for someone to assist with what could be wrong and had no reply. This has delayed my work and my older router/device was much faster at 20mgps, no delays. The worst part is that no one is assisting with support and responding to anything. I want to be able to have someone contact me to correct this or refund my money, it is so unprofessional and seems like I was told and sold more than what this actually can do. Even the adverti*****t on the website states what you will be getting and also allows you to check coverage and it has been so misleading overall.
