Credit Card upgrade scam

I get these so much, it’s unbelievable to how they’re still going. Just got one today and annoyed them to hell. One of the dudes literally just outright cussed for 5 whole minutes and I couldn’t stop laughing in his face.

920-xxx-xxxx

I just realized that the number they used was spoofed and I had to edit this beforehand to censor it and not let innocent people get baited wrongly. These guys spoof numbers every time so it's difficult to track them. Sometimes they have their own numbers but it's bad enough they're using people's own numbers for their scams. Total jackwads, I tell ya. How can I better track down these idiots if they use spoofed numbers?
