PowerNet Global review: long distance carrier 1

I've used their long distance services for years, but there was some company change over a year ago and since then the rates have gone up without notice. My local phone company now has better rates than this company. Recently the intrastate rates were raised to 25 cents a minute. WITHOUT NOTICE! (From reading other reviews this seems to be a M.O.) Since I call in state more than out, and after receiving an unexpectedly high bill, I changed my long distance carrier quickly at the local phone company, but I still got a bill later for basic service and taxes even though I'm not using them anymore, because I failed to call Powernet Global to cancel the service. Customer service was cold and rude, but not unexpected considering they likely have to deal with other dissatisfied customers. I'll happily pay the local phone company rates to be free of this company. I am taking the time to find every review site I can to let folks know about this "alleged" HA! rip-off !
