The number belongs to a debt collection agency called Baycorp. I got called on a private number and I refused to give personal details. The woman said it was regarding a private matter. She supplied this number I could call her back on. I didn't as i suspect it is a scam

Caller: not call but letter

I have received a letter from a company called Baycorp and they want the debt to be paid immediately, like Jacinta's case they only gave me a number to be called back and reference number. Probably this is a scam

I have received about 8 calls so far from this number. They give no details other than a reference number and request to be called back.
Bordering on harassment.

Caller left message with this number and gave a ref num to quote but left no company name or who he was?
