I have. As a very dissatisfied customer.
I now use only friends and rabbonim because the “professionals” are just shooting arrows at dart boards. If I would have been forced to pay one in particular, I would have looked for a heter to moiser her to the tax authorities after I paid her, so as to put her out of business once and for all. Another one tried to cheat me in an unrelated transaction after wasting my time; she is a participant in all kinds of MLM and alternative healing scams and wanted my services to help her market her scams. I sent her a very sharply worded message telling her to quit making a chilul Hashem with both her shadchanus and MLM scams.
The only honest one I dealt with was a brother of 2 friends of mine, who realized right off that the 2 of us were better off becoming personal friends than his trying to find me a shidduch because he isn’t a full timer and really handles only younger people from families similar to his own.
If anything, the only shadchonis I would have paid was a very well meaning personal contact who tried, made a real effort, and was rebuffed by the girl’s parents probably because of yichus issues. If it would have gone through, I would have sent her a gift from an online or other delivery merchant, because she told me right off that she would refuse payment as she’s not a pro and was doing it leshem mitzvah. More people like that, and fewer shidduch plumbers, and the crisis would be abated quite substantially.
