Vokintag Associates review: They somehow found me and offered really dangerous deal 1

I got the letter from the company Vokintag Associates. They offered to sign the contract with them. The rep told me that this contract would bring large money and it was profitable deal. I thought and was confused that they wanted to get money for something, and they wanted to get this sum immediately. As well as they didn’t reply where they have found me. Really strange, so I wonder maybe someone has any experience with them. Please, post comments.
