Caller: Some little scamming c*nt

Some little bastard called me from this number saying he was from the "Mastercard and Visa Security Department" (lol, right?), told me there were purchases from my account, one at eBay for $300 and another $900 transaction. After I said "Hang on, you're full of sh*t, aren't you?" and then called him a "thieving wanker" and told him off for trying to steal from people, he hung up. Watch out!
