sergio mendez lawn service

Sergio was referred to my by my sister - he mows the lawn where she works. I had several trees removed and my front yard was in a sad state. I was considering a total resod - but Sergio indicated he could repair the yard cheaper than new sod. Est for just the purch of sod was approx. $900 + labor which my spouse could have done. I had an issue with crabgrass and creeping Charlie - which I did not feel could be resolved by re-seeding but Sergio indicated he could fix this. I repeated requested a bid for cost of repairs and was told it would me much cheaper but never rec'd an estimate. He advised it would be forthcoming and cheaper than resodding - so I agreed. Sergio showed up when he wanted to with no advanced notice and proceeded to complete work - which was spraying yard, adding top soil and reseeding. after several weeks he advised he was done - and told me the cost was $920. when I went into shock he told me that seed cost $170 and 7 loads of topsoil were used at $60/load....but of which are exorbinate charges but he only charged me $300 for labor. He also killed the English Ivy under my pine tree which I had not approved. Silly me, I paid the bill, but did request a further spraying and continued advice on lawn process which he agreed to. After several weeks I noticed the lawn was not proceeding as planned and asked him to stop by and consult....after a week or so he showed up unannounced in the middle of a party and sprayed the front yard....which I believe he oversprayed to kill whatever was growing due to my dissatisfaction with his service. I told him of my concern and dissatisfaction and he indicated the continued problem was due to my dogs urine....this is a 12 yr old beagle....who we purposely put out back so as not to interfere with lawn. He left without notice. The only thing now growing in my front yard are weeds which I have spent numerous hours pulling to try to get the problem resolved. I have also spent another $100 +/- in additional seed and other lawn cures. He never showed up again. Please see the difference between my front & back yards in photos attached.
