Got a call from these ppl today too. Have a feeling who they are: Wells Fargo. Main office is in Des Moines and the ID said West Des Moines, IA. They called every 15-30 mins all day long.
There were multiple calls to my cell phone from this number over the past few days, with no message being left. I don't owe anyone money, so I don't even have a suspicion as to who they are......
