The pool service guy that does my monthly pool cleaning put a mechanics lien on my property. In July our filter stopped working and our pool guy said it was because we needed a filter cleaning, and that it would be $75.00 extra. We agreed, and after he completed it, he said that it wasn’t the issue and that we now needed to do some re-piping to the back on the filter. He said that would be an additional $200.00. We agreed again, and he did the work. Our bill arrived for $445.00 ($100 regular service, $260 pipe repair and 85 filter cleaning.) I disputed the amount because it was higher then we were quoted but he only took off $10.00, and said it was more because he spent time researching how to do the re-piping. On top of this my new pool guy said he did a bad job and is now going to charge me more to fix it. Despite this, I sent him a check the first week of August. Unfortunately, I accidentally switched 2 numbers in the address line and just received the check rendered “undeliverable” back in the mail from the USPS. On the same day, I received a Notice of Mechanics lien for sum of $628.00. The pool guy never contacted me by mail, email, text or phone to let me know he hadn’t received payment. Since receiving the notice I have called, texted, emailed and tried to deliver the original check in its returned envelope in person to prove that I had tried to make the payment in good faith and it was just a simple mistake. Despite my attempts, he has not responded at all. I want to settle this, but I don’t know how to if he won’t respond. What are my options? I feel like I am being ripped off with all the fees he is adding.
