Not sure what to do with this realtor?

[Brian Rowles]

I am not sure what to do looking for advice. I bought a house December 31, 2018 from a realtor in Indiana. The house was rehabbed and put back on the market with the same realtor on May 24, 2019. The house was shown 57 times with no offers. I asked my realtor to Have an open house I wanted it blasted on social media and an email sent to all local realtors that I would be taking offers over a certain amount, which was about $15,000 less than asking price of 79k. I want to make a big deal out of it was going be cooking hamburgers and hotdogs etc. etc. Basically she told me that she thought I lost faith in her ability to sell the house and she thought we should part ways. That was about a 12 days ago. I signed the mutual release send it back to her, she received it took her signs down and left me the key. I put the house on Facebook marketplace had approximately seven showings in one week. A young couple wanted to make an offer so they got a realtor to make the offer. Their realtor went into the MLS system and saw my had realtor never took her name off of this listing so he contacted her for another showing this morning. She allowed him to show it and they made an offer. now she wants her full commission even though I bought the couple to the deal and the only reason she was contacted was because she never took the listing out of her name. Is this a normal practice? Do I have any recourse in this situation or should I pay her the commission and be done with it?
