I spoke with them just now! They knew exactly what and who I was talking about and they provide phone services TO the telemarketing firm/call center and all of those #'s are INDEED the ones they provided them with, and they are all the ones they use to call! They said they've gotten complaints all day today and all month and last month, in fact!
Call them now!
Called twice and left this number on our caller ID 408-651-8124. Contacted the Digicom corp and complained at 800-464-5446. We are on the Donotcall.gov list. We also now have Google Voice that permanently blocks both them and Digicom and now our phone won't even ring when they call.
