Called and left no message. I don't answer unrecognized callers. Since I'm the only one reporting this number, I'm not yet ready to block the number. If they have anything important, they can leave a message and I'll call them back. If they are calling other people with nuisance calls, I hope it will end up being noted here.
I did google the number, and it appears to be associated with something called merchant circle. There's not enough info to go on yet. I'll be checking back.
