Bad Customer Service.

I had upgraded from 4G to 5G with Rain, they had swiftly delivered my new router and sim, almost immediately disconnected my 4G sim, but I just couldn't connect to the internet. I contacted support, they asked for pictures and advised that a technician would come out and assist then they went ghost. Called customer service and the agent convinced me that I'm the one doing something wrong until I got irritated and asked that he call me back, he never did. Contacted customer support again via email, someone notified me that I've been issued a duplicate sim and it needs replacement and asked for my delivery address. That was the last communication from Rain, they no longer respond to my emails, it's been almost a month without internet.
