An ex-vendor provided security services to our property for 2-3 years. In March or April of this year, they came to the conclusion they billed us incorrectly for virtually all of 2020 and sent us a bill for $8k to make up for their apparent error. After requesting proof of the incorrect billing to support their case – they never provided this. Furthermore, we asked for a copy of the contract that says they have the right to do this and can place a lien on our property for non-payment. To no surprise, they have not produced a contract. We ended up terminating our arrangements with them. Now…they are threatening placing a lien on the property through Level Set We have never received a Pre lien notice
