Scammer?

[poker]

When I got into office today, I noticed 3 missed call on my office phone. All 3 missed calls were made from the same number. I thought to myself, why didn't that person call me from my mobile if it was that urgent.

I called the said number and someone answered after a few rings. I said, I got a missed call from this number, who is this and how can I help? (The reason why I bothered to call back is because I work in a multi national company and it is pretty common for my other colleagues from other offices to call me.)

Anyway, the person who answered and was pretty hesitant. Then he said, my name is XXXX from Nigeria and I sent a proposal to your company. It is regarding a project in cooperation with the United States and World Bank.

I suspected something amiss and asked him, which company did not you send it to? What is the name of my company? He was unable to answer. So I said, thank you and bye bye.

I think I caught them off guard by calling back and they were not prepared with the script. Anyone have a similar experience to share?
