I've gotten two calls from this number. Didn't answer last time, and they didn't leave a message. This time I picked up out of curiosity, but no one was there. Said "hello, hello?" a few times before hanging up. Number is based in Plant City, Florida.
This is a scam. They call from one number: 877-236-5791 and then after that call ends, immediate from the 813 number.
Not sure who they are (I am not past due with anyone, nor do I have any collection accounts, nor have I signed up to buy a house/car/boat/insurance)...
