I had a lawn care company come out to shoot grades for my lot, they claim they did and charged me for it but I can not prove that they actually did. The survey drawing they provided me was after three months and it was nothing like we talked about or agreed to. The 'survey' they provided was not to scale and was inaccurate and based on questioning the vendor I feel very strongly the measurements were never taken. I disputed the charge on the CC I used and the vendor is not threatening to file a lien against me. Does he have grounds since no improvements were made?
