I just answered a call from this number, I let them ramble on trying to sell me on Allstate's Auto Club membership for only a dollar a month. They assumed I wanted it, and asked me which type of card I wanted it on. I said I would pass and then they tried to sell it more and asked for my card again. The third time they asked I had hung up on them.
Anyways, I don't think it's Allstate, probably a scam. They did have my address and number, but I'm sure that's not hard to get. Their phone quality was poor and scratchy like a bad cell phone. They tried to push for my credit card really hard.
Allstate Motor Club. This is an outside company that sells motor club, I know this because I sold this for two weeks as a telemarketer. They do not represent the company, and although it could be a decent product, the idea is that you forget to cancel after the first month (for a dollar or whatever) and then auto bill for the actual amount.
