I would like my refund

I made a booking to this property in Lorraine but I called the property and asked if visitors are allowed since I was going to have 2 of my friends visiting . The lady said visitors aren’t allowed and asked me to cancel and she will also cancel on her side , I did the cancellation and the cancellation was confirmed . But before I cancelled I asked her about the refund she said I will get a refund but doesn’t know when the money will reflect since booking.com handles the refunds. I waited for about 12 days since the waiting period for a refund is 7-12 days . I called booking.com and one of the agents said that they can see that I’m suppose to get the refund cause I cancelled on time and everything but the lady needs to confirm the refund on her side before they send me any money cause the money already went through to the lady . So the agent who helping tried calling her but the lady of the property didn’t answer and I also on my other end tried to call her but it goes straight to voicemail, i waited cause the agent sent her an email but when I called booking.com the second time they said she rejected the email they’ve sent but they will try to plead with her to accept the email. I also emailed her and she responded to my email telling me that she doesn’t handle the payments I must contact booking.com that’s what she said to me on her email . I answered telling her that booking.com has been trying to get hold of her she needs to respond and confirm on her email she didn’t respond to my email , I contacted booking.com the third time and they said that she hasn’t responded to any of their emails yet and they can’t get hold of her number where I assumed she changed her number cause I also tried contacting her cell and it always went straight to voicemail even today . The agent told me they’ll try emailing her again and wait for her response otherwise they’ll have to use legal services or I have too I’m not sure I didn’t hear that properly though but they mentioned legal services though . Today is the 2nd of July a new month and I still haven’t heard anything back and now booking.com has been placing me on hold . I need help with this matter cause I need my refund please
