I received a call today from (406) 219-2085 and when I questioned what card they were calling about "Tammy" hung up. I Googled Card Services and got a legitimate operator with Synovus and their affiliates. She said it is a bogus call and that they would NEVER call their customers. They would send information directly to you in the mail with your card name and account number. DO NOT GIVE THESE CREEPS ANY INFORMATION.
Have had two calls from this number in a few days. I pressed 3 the first time the call came. This was supposed to stop further calls, but obviously it didn't. The spiel is for lowering credit card rates.
