I could barely understand what this scammer was saying. Generic refund scammer. These numbers might be in the same call center. I screwed with the 956 number with a soundboard for about ten minutes in single call. The toll free number called during that.
When I called it back someone in the background sounded like he was telling him to hang up or something. Then he disconnected. These two numbers are probably the same people.
The guy who answers the 956 number had an attitude the moment he picked up, and this appears to be one of their numbers they use to make outgoing callback numbers. It does receive text messages, but I don’t think it’s Textnow.
