Rain nonsensical customer service and signal

I have been experiencing internet issues since yesterday, today it got worse and I called the rain support desk. I explained my issue and the lady told me that the current tower has issues and said she will connect me to another tower. An hour later I called rain again as the internet connection was worsening and I was told there are no issues on their side and I need to find a suitable location and optimize my router. I requested a technician to be dispatched to assist as I have moved the router around the whole house but I still battle with signal and the supervisor informed the agen that won't be done I must sort myself out.

This is very disturbing as I won't call and ask for assistance if I can solve issues. I'm not a technician and I believe rain should render a service which we pay for monthly.
