Is my client messing with me?

I’m doing a few grad shoots in LA and someone reached out through my ad. After going back and forth for more than a week (her asking for a cheaper price despite my already lowered price) she wants to do it. But I’ve asked her to send me the signed contract +$75 deposit around 5 times and she sends me illegible scribbles and didn’t even bother signing her name or printing her name.

Is she just messing with me and should I drop this client? I’ve never had this happen to me before
