I have, twice. I've also had a tech out to my house, spoke to a tech on the phone, and emailed "Amanda" who handles complaints from Facebook. Everyone says the same thing: problems due to over-utilization, ETR 2013, but no estimate of when in 2013.
I was beyond irritated already but then to hear from 2 others living on my same street with no issues just kind of makes me feel like I'm either being cheated or lied to, or both.
