Our DSL modem finally arrived today. Well, it kind of involved accosting the UPS guy in an adjacent street whilst walking back home from 7-Eleven acquiring ice cream, but hey, we got the thing in the end.
I went with Sonic on advice from guys from work, and I have to say I've been totally impressed with their customer service to date. Today I got an email from them because I'd reached my activation date, but they hadn't seen any ADSL traffic from me yet, and they just wanted to check that everything was okay.
We had a free dialup account for use while we waited for the ADSL to be provisioned (and the delay was with receiving the modem over the holiday season, not the ADSL provisioning itself). Also, their account management website allows an impressive amount of self-control over aspects such as spam filtering and firewalling. I'm a very satisfied customer so far.
