predicament

so ummm yesterday this lady messages me on insta, and asks me to draw her, (my insta has my art on it) and I don't have a PayPal, so I agreed to draw her for free since she has more followers than me and it might be good for my account cause I don't have that many followers. so I asked for little bit of time cause I don't have a sketch book at the moment and I also asked for some reference photos, she then told me to just go to her account and look at some of her posts, now I normally wouldn't have a problem with that its just that SHE ONLY HAD ONE POST and it is so heavily edited with really bad filters I can barely see what she looks like so right now I could just be drawing a picture that looks nothing like her so I messaged her saying that I need some unedited pics of her, that was 3 hours ago and she still hasn't responded yet. what should I do ?
