This call is from Wellsfargo card services. It's their automated call services. They call about 3 times a day, but they don't leave a message. When you do answer, they hang up. If you call back it goes into a recording. It's their way to bug the hell out of you until they get what they want. This is their form of a collection call. They are not supposed to contact you at your place of business, so they will interrupt your business day with annoying calls.
