No service at all

I have been with rain for 2 years now and been at the same location. So previously I was on their LTE(4G) and the service was great even referred few people. Now I decided to move to 5G, I have checked coverage covered, delivery, and taking money from your account super fast. Now here is the issue the damn router is not connecting and have moved it around, they suggest that you should install it outside for better service but still not working. The worse part the whole stuff is on lockdown the only way to contact them is through that useless support which no is responding. Now it's been over a week no internet and no one to assist you. There's nothing I can do at the moment I can't even cancel the service all now what they're waiting for is Month-end so they can bill. I'm really disappointed
