Unprofessional and Rude
Don't sign the free invoice. THEY ARE ABSOLUTELY HORRIBLE!!!! There service is a joke. DO NOT EVEN BOTHER. Also DO NOT ACCEPT THE INVOICE BY E-MAIL. It is a trap. You are not accepting an invoice you are accepting a 6 month contract for service. Be advised that the owner is rude and will not let you out of they contract if you mistakingly accept what you think is an invoice. Be warned. Please choose another company for you lawn care needs.
If they were such a good company, they would not need to trick consumers into a contract.
