Yea totally agree with you buddy. I am a customer for probably over 1 year now and they were spot on, the rotating proxies are amazing, sometimes they are a little buggy but no big deal. I didnt have any issues with them at all, but like you said. In the last 2 months the proxies were just getting worse and worse. Last week was probably the most problematic one when all proxies stopped working. The support is pretty fast but they don't seem to care really much that the customer is unsatisfied with the constant crashes of the proxies.
If its not their fault then i can understand the issue, but a little bit of a update for us would benefit them as well. Atleast then i know its not their fault that the proxies don't work..
