"Retention Department" on the caller ID. Calls at least 1-2 times each week. I just filed a complaint at https://www.donotcall.gov/default.aspx. Hopefully enough complaints to the FTC and these guys will be shut down.
I'm sure this is yet another spam/scam call. It seems like the phone rings with fake solicitations and 'power companies' wanting to lower your rates more than actual legitimate calls.
