Unburied internet wire on my property

I've been going back and forth calling and trying to message ATT to come and bury a line on my property, but, in keeping with their tradition of absolutely terrible customer service, they either can't find my house, or don't know who to transfer me too every time I call.

So, how can I get them to come bury this line before I mow over it and end up cutting it and switching internet providers.
