I just found out from our new account manager with AT&T that we'd been getting charges on two of our phone lines by this Silv Comm, through USBI. Through AT&T, we'd already had a deal on all 10 of our lines for unlimited long distance for a flat rate, but I never noticed that this new charge started appearing with the February bill. We'd recently switched back to AT&T after a brief time using another service, but the bills look a bit different now with AT&T and I'm sure that added to me not noticing. Neither I nor the administrator of our nursing home authorized any changes to be made, and I'm very careful when listening to folks trying to scam me. I've heard quite a few good ones over my 11 years at this job. I usually have a bit of fun with the "We're with the copy machine . . . " scammers before they get frustrated and hang up. Somehow these guys managed to get their hands on 2 lines and charge us almost the same fee for 2lines as we were getting charged for all 10 lines combined for long distance. Be careful out there.
