I'm an awful person??

So I kept getting these calls from this woman looking for my MIL and I told her she no longer lives in my home. She goes oh well, maybe you can help me and I say ok? She wanted to send me a packet to donate for breast cancer. The packet price options were pretty high for me right now. Their lowest was $100. Plus, I didn't know if it was a scam or not. I told her I am sorry that I can't do that right now and hung up. She called me no less than 5 times with all the same info looking for my MIL. This also was not a recorded message. The last time she called I asked her to please take the number off of the call list and she literally told me "ok, thanks for being an awful person and not donating for cancer" and hung up?! Like seriously WTF?!?!
