An academic recently wrote a question, and I went to answer it, but it appears he deleted his question (probably out of embarrassment).
It concerned what I call "Vampire" publishers. This academic paid some money to an Indian journal but they had "not received" his money and he was wondering whether he should be worried. That was his question.
These "publishers" are becoming a problem. The academic need not have been embarrassed as forums like these are a good way to expose them. So I will raise the question again for comment.
I am not asking so much if people have been conned by these malicious "journals", but I am asking if you have been approached by them. I am interested in ascertaining the magnitude of the problem. I am also trying to expose these practices in a public forum for younger scholars.
My response is given below.

"Vampire" publishers are now rife. They send you a nice email explaining how they have read your paper X, and they flatter you by saying how they respect your expertise in area Y. Then they offer to publish a piece of yours in return for a small fee.
No journal worth its salt will ask for money. Journals that do are not worth your attention. Being published in them will add nothing to your CV.
It sounds like you have been conned. This is the academic equivalent of the "Nigerian letter" scam. If your work appears at all (and I doubt it) it won't be recognised as a legitimate publication by real scholars. Their impact factor was probably made up just to impress and to get you in.
While top-ranked journals are annoying in their insouciant attitude, and take forever to publish your work (if they ever do); and they have endlessly long peer-review processes, they are the only ones to aim for.
Put it down to experience. Good luck.
