Rugs Cleaning Brooklyn

I paid Rugs Cleaning exactly what they quoted ($ 350 plus tip, unfortunately, in cash). First mistake. The one cleaner who showed up sprayed a solution on the rugs and then vacuumed them with a machine that sucked up the solution.
When he was done, he showed me a container of grey liquid. I pointed out some areas and borders that did not appear clean. He told me to wait until the rugs dried. I did.
THE RESULTS WERE AWFUL. The rugs were worse than before the «cleaning», The colors used to be bright but now there is a dull haze as if the liquid spread the dirt around.
I e-​mailed Peter to complain and he did respond. He asked me to send photos to verify my complaint. I did. And that was the last and only communication I received.
I called and left at least 10 messages and e-​mails. And then, in frustration I walked over to 212 W 82^nd Street to the «office». The building is a residential apartment building and no RUGS CLEANING was listed on directory. There was no Peter Somebody either. They advertise that they will come to re-​do the job to the customers satisfaction. I doubt that this company exists because they are nowhere to be found.
This experience was a rip-​off. BUYER BEWARE ! DO NOT USE THIS SERVICE.
My rating is minus zero!
