I received lots of calls from this number but no voicemail was left. Then I answered the phone they asked for someone else, and said they were "returning a call". I said wrong number. Two hours later they called back with the same story. Sounds fishy to me, but maybe they really did just have a wrong number.
Received call. No voicemail left. Thanks Patty Dunn for the detail. If it was Direct Buy, I know I gave them my number a month ago. Not happy with these calls.
