If these people are calling for "credit card service" then I know for sure it's a scam. I only have 2 credit cards one through Goody's and one through Walmart and neither of them call me they send me emails. I hate scammers.
Got a call from this number while i happened to be sitting at my computer so i googled the number as it rang and it came up on this website. i clicked the link to read the comments. as i suspected, it's a bogus number. i didn't answer and there was no message left. my caller i.d. said 'survey'. it is now a blocked number on my phone. i really appreciate this website and the comments left here by others. thanks.
