RAIN Bad Service

I have a new 5G uncapped wifi deal with Rain, out of 6 days, the wifi has worked for 50 % of the time. All they keep saying is, the towers are down. This is the worst service ever as they don't call back. I have left endless messages on Facebook and my calls have supposedly been escalated. I would much rather get a new service provider. This is certainly not worth it!!! How am I supposed to get any work done from home, when there is no internet!!! How can you towers always be DOWN???
