Right, so long story short - Scammer got hold of my GF's number, rang her then tried to get her to upgrade our UPC TV package (I only have UPC BB, not TV) cause they had a super limited special offer that was only good for the next 40 seconds.
She told the guy that she doesn't pay the bills and that it's me he needs to contact, so she gives him my number :rolleyes:.
I get a phone call stating that I enquired about an upgrade (which I didn't) and that it was only valid till midnight. Asked for my CC details straight out so I told him I was making dinner and would call him back later. He's since phoned me 3 times and left a voicemail.
The guy phoned me from a mobile number (since when does UPC conduct business through a mobile

)
Anywho, I'm not asking for scamming stories, just for a way to f*ck him over. I've obtained 2 phone numbers (not sure if I can post them). The plan is to sign both of the numbers up to as many free spam text company bullsh*t that I can.
Any other suggestions?
TL;DR - Have 2 numbers of a scammer, how do I f*ck him over?
EDIT to include number: xxx
