Calls several times per day, but I don't answer since I don't recognize the number. I decided to google to find out who this persistent caller is, and came across this site. I don't use credit cards, so this can't be a legit collection. I suspect it may be the same scam artist who hacked my bank acct. a few years ago and then tried to scare me with threats after I closed the account. They've even tracked down relatives & threatened them. Beware!
Caller ID for this number says Owens Corning--an insulation company. We have used the insulation for our home, but purchased it at Menards with our bank card. If it's a debt collector, they probably shouldn't use the caller ID of an entirely different company....
