Austin 311

This is a note left on my door saying they need access to my back yard. I will not be leaving my gate unlocked.The city needs to require professional communications as a part of the agreement in order for a vendor to have access to an easement via my private yard. I will NOT allow anyone in my yard based on this. Please see attached. Also, it is impossible to get in touch with AT&T to check the legitimacy. I don't have an account and I'm not sitting on hold for the 39 min wait time quoted
