720-315-7901 - Aggressive Telemarketer claiming to call on behalf of Century Link. My receiptionist screened the call the first call, and the guy became very aggressive and started making veiled threats if she did not put the person in charge of phone services on the phone right now. I answered the 2nd call myself and a guy told me to get F&CK3D when I started asking who he was.
If they are working on behalf of Century Link, then one more strike against Century Link for hiring a shady telemarketing company to sell their products.
