I've been told that the company is called AppStar and they are trying to get you to change merchant accounts. From my own experience, they don't speak up, blame you for calls being dropped or hanging up on you, and relentlessly continue to call you to the point that it's up to you to block their number.
You can call them back at the number (855) 409-4569 and dial in your own number after the message to take your number off the list. Asking them to do it for you will get you nowhere imho.
App Star is the name of the company.
I asked them to remove the number from the calling list and they immediately hung up.
