Realtor not responding

I called 3 realtors from different brokerages re selling my 2m$ house . Left name, address, and reason for calling. They’re all well known luxury home realtors in my town. Two responded and viewed the home, brought materials and discussed the way they work. One even showed it that weekend (not ideal, but I didn’t want to be uncooperative.) The third one called at 10:30 PM after two days, left no message. Then called 2 days later at 8 am, no message. I wasn’t near my phone either time. Upon seeing the 2nd call, I called back, wherein the realtor pretended not to know my name, “I know a helen peterson.” she said. “Oh, well , I am jacqueline peterson.” I mentioned the two calls. She just laughed and said, yes, odd. Seemed to care less whether she saw the house, but eventually said she’d come by the next week if I wanted. I have never met this person nor sold a home. She’s clearly disinterested, but what is with the weird treatment vs simply saying , “I am not interested at this time.” Or something similar. Or am I reading too much into this? I declined to meet.
