!!!Ugh!!!

Okay, this is just the kind of thing that happens to me. Stacey is selling some pressure cookers on Craigs List, & my cell was listed as the contact, as I was off last week & more able to take the calls... Well, I worked this weekend, & the number was still on the listing, not too big of a deal, I was able to manage the calls that came in, or so I thought. I received a call about a pressure cooker on saturday from a young lady, who was really just being the relayer of information from the man she was with, I could hear him in the background with the questions. There was a lot of back & forth, some phone interference & lots of wind, I could tell they were out & about. They had all kinds of suggestions about meeting in other parts of KC, so they would not have to drive all the way from Olathe to Lone Jack. I had to explain a couple of times that I was @ work & unable to transport the pressure cooker & I didn't want my husband to load up the kids to go for a long drive himself. At one point I thought they asked if they take 50, I said "yeah, you take 50 highway". We arranged that they would call me back for directions after they finished their current errand, they called back, I gave directions & they got out to the house to get the pressure cooker. But that's when Stacey calls me to ask how much I told them for the pressure cooker, I said "we didn't discuss price, so it should be $75." Well, they left the house & immediately called me, & we tried to figure out why they thought we had discussed a different price. That's when I realized it was when I said "yeah, you take 50 highway." They were not asking if they take 50 out to Lone Jack, they were asking if I would take $50 for the pressure cooker. Well, I did feel bad, but some people don't make it easy to work with them. This young lady was nice, but in the background, I heard the man say we should owe him $15 for the long drive out there, and then she asks if we will take $60. I tell her no, that I'm sure we'll get the $75 for it, but I feel bad. Stacey felt the same way, we wanted to work with them, but in the end we just let them keep going, because it was just a misunderstanding, & then there was the suggestion of entitlement that I didn't like. So, today, I get this text from their number saying "I hope you know that I have turned you guys in for fraud." !!! Ugh !!! Now I am probably thinking about this, & having more angry feelings about it than they are. Also, I don't feel comfortable, because they have my number (if they chose to continue to harass me), but more worrisome, they know right where we live. This will probably all amount to nothing, they will probably do & say nothing else (I'm sure there is also no claim of fraud anywhere out there). But right now I am very bothered. does anyone have any suggestions?
