I received a call from this number and didn't answer, but called back from a landline. There is an option to have your number removed so if you do call back just listen to the prompts.
I just received a call from 314-627-6808 and they did not leave a message. I called the number back and found that the company's name is WCA Subscription Center. If you follow the directions, you can remove your number from their data base.
