Cannot contact Lender to pay Mortgage

[Kyle Bigger]

I have a house under seller financing, and if I go six months without paying my principle/interest, the lender (seller) can call the note due.

Here's the issue, I've went to her house, tried to call her (countless times), and I can't get in contact with her. I do not know if she is doing this on purpose, but I need a way to remedy this.

Funds are not an issue, I just need to be able to pay her or have a mortgage account setup, but I can't freaking get ahold of her. I have about 3 weeks left. If I don't figure something out within the next 3-4 days, I'll just call a lawyer.

Any advice?
