Rain Rip-off

I have started with Rain with just the basic package which didn't serve it's purpose at all so I upgraded to the first level of uncapped.. It was amazing for the first few months and suddenly problems started and Rain advised me to upgrade to the current package of uncapped which offers 50Mbps speeds. Again it was awesome for a while then the problems started again and Rain cutely advised me to upgrade again but this is when I realized that they will just keep doing this. I have not upgraded and speeds are getting more ridiculous every day.. I'm starting to BELIEVE that Rain is a total rip-off..
