Can you guys tell me what to do about this nice old lady?

This lady, named Emma, somehow confused my number with Meals on Wheels. It started a couple of weeks ago when she called and said, “This is Emma? Are we not having dinner tonight?”
I asked her who she was trying to call, she told me. I looked up the number for her (which is no where NEAR close to my number) and gave it to her.
She was really nice and thanked me and apologized.
45 seconds later the phone rang again, and it was her again.
It’s happened a few times since. It’s to the point we’re on a first name basis.
This morning, at 7 a.m., Emma calls and asks if Meals on Wheels will be delivering due to the snow. I said, “Hey, Emma. This is Val again, not Meals on Wheels.”
She repeats the number back that she thought it was. “2466?” I said that was my number. She said, “Well, maybe it was 2566.”
Again, she apologized very nicely and we hung up.
45 seconds later, the phone rings.
I let it go to voice mail.
A few hours later the phone rings. Emma says she wants put in an order for Roast Beef tomorrow.
I say Roast Beef sounds good, but I can’t help her because I’m not Meals on Wheels.
We hang up. She calls back. I let it go to voice mail.
Just a moment ago (this evening) I had a voice mail from her saying she won’t be in for dinner because the schools are closed. ???
I DON’T KNOW WHAT TO DO!!!
