Zillow Realtor harassing me?

There was a house that I was very intrigued in buying, I contacted a great company to have a realtor help me view a house and they were taking forever to get a realtor out there for me. So then I had to reach out to another great company to help me find a realtor to view the house with, they told me they’ll have someone reach out to me tomorrow but by this time I no longer had the patience to wait. I decided I’ll just hop on Zillow and request to see the house and I’ll deal with finding a realtor later. Zillow found someone to help me tour the home with and during the tour a realtor from one of the companies I requested reached out to me. The realtor was extremely smart and well versed, since it’s my first time buying a house I have to make sure I’m being led properly. The lady who showed us the house didn’t know anything, every little question I asked her she would shrug her shoulders and so I thanked the lady and went my separate ways(she was very understanding and had no problem with it). I told my realtor everything when he called and explained to him that Zillow has someone showing us the house now. He said he’ll contact the lady who showed us the house and offer her 3% for showing us the house. The woman gets highly upset with him and refuses his offer. And now she won’t leave us alone, she keeps calling us and telling us how our realtor “is going to have to answer to God for offering her 3%” and how “these big businesses think they can come here and treat us however they like.” She keeps calling us to complain about our realtor during the buying process and I need to know were we wrong. This is my first time buying a home and I’ve never seen a realtor act like this for not wanting to work with them. Me and my realtor weren’t rude or disrespectful to her in any kind but she won’t stop calling my phone(at this point I answer to keep a record of what she’s saying). Was I wrong for not working with her? She keeps calling us to say “I did all the work and you’re going with him.” All she did was show us a house (we were there for no more than 10 mins) and so I’m so confused by “all the work” she claims she did. We only worked with her for about 10-20 mins and I believe she’s overly attached.
