Though it may be a painful few weeks until I get another service, I have up and cancelled my DSL service from Frontiernet. I actually managed to get them to refund two months service this time, as my last call to their customer service department beared no fruit (I didn't really try hard that time, though).
So goodbye $50/month DSL. Goodbye days with speeds worse than old school AOL. Goodbye extremely rude tech support. Goodbye unskilled tech support! Goodbye days and days with no connection at all. Goodbye being told to buy a better package if I wanted better service!
It looks like I'll be getting a wireless broadband connection, as there's an outfit here in town that offers the service. Should average 512Mbit synchronous! That will be nice. Perhaps I'll finally get around to hosting one of the domains I've leased!
