Debt Collector for unidentified debt.

"Hello, [name].  My name is Olivia Hartwell.  Please call me at [phone number and extension] before 5:00 p.m.  When you call you will need the reference number [ ___ ]."

Nice, charming genteel Southern accent.  Obviously a debt collector, though; and asking for a person unknown to me.

I say, let 'em waste their time and money chasing after someone who (I'm assuming) gave them a phony number.

I received a call from Olivia Hartwell too, stating it's important that I call them back before 5PM.  They gave me a case number, no idea who this is.  I don't owe anyone anything.  I'm not calling back.

These idiots are trying to collect on customs duties owed to UPS for an international shipment I made. The only problem with this is that I only make international shipments with the post office. I use UPS for domestic only. You can't get them on the phone but I would like to call them the C word because that's what these scumbags are!

I called that number back and referenced my account number they left in a message. she informed me i was a contact on an invoice they were trying to collect. i will be keeping a close eye on my phone bill in case it is a phone hack scam. she apologized and said she will not contact me again. i would suggest just deleting the voice mail and hope they quit calling.
