tl;dr: skip to the question at the bottom if you don't want to read this story.
Years ago I received an email from a man who told me he was a really good car mechanic. This was fantastic timing since I had been having trouble with my car recently, so I replied to his email and explained the issue to him. He knew exactly what the problem was and said he could definitely fix it, and it would cost me $250. I already had a quote from another mechanic for $2000, so this was a really good deal, and I agreed.
The man told me where to meet him, so I brought my car there, and gave him the $250. Since it was going to take a day I had my friend follow me and drive me home. The next day the mechanic emailed me and told me he found another issue and it would cost another $500. He gave me a way to pay him online so I didn't need to have my friend drive me over to pay him, so I paid online. 2 days later he told me he had fixed my car and it was ready to be picked up, but he found one more issue which he fixed too, and I needed to pay him another $500. I told him I didn't agree to the last fix and he said since it was already done, I either needed to pay the extra $500 or he wouldn't give me my car back. So I had my friend drive me to meet him, I gave him the additional $500, he gave me the keys to my car, and he drove away.
The weird thing was that my car was in the exact same place where I dropped it off. It had snowed the night I gave my car to him, but there were no tire tracks in the snow, and no foot prints around the front or back of the car, as if my car had never even moved, or been touched. I suddenly suspected that I had been scammed. Sure enough, when I turned on my car, the original problem was still present. This guy had scammed me out of $1250 and never even attempted to fix my car!
Disclaimer: this is a made up story. Did you suspect this story was a scam at any point before fictional "me" did? If no, then you just learned something. If yes, why is it easier to detect that this story is a scam, more so than an online stranger offering to invest money for you and beat the market?
I hope now you can answer your own question:
I am not able to understand that why company is asking same thing. Is this company running a scam team to scam people like me?
Yes, absolutely. They are saying you were scammed to earn your trust, so they can try to continue to scam you.
