After being very happy with Rain, I'm now disappointed...

I have been a very happy rain customer for many years. I have recommended rain to many of my friends too. Unfortunately things have changed. I'm paying a lot for the top speed uncapped but I'm getting 5mbps and if I reboot my modem I get 30mbps for about 20 mins and then it drops again. I should be getting close to 100mbps. Over the last 3 weeks I have submitted 4 requests to deal with my slow internet speeds... Ticket #***1 #***9 #***1 and #***2 Unfortunately the matter has STILL NOT BEEN RESOLVED. I've only had one email from a human being - all the others are automated. The AI on the website is polite and intuitive, but it doesn't lead to action. No-one answers the *** number either... Warm regards, Theo
