I privately listed a rental property and immediately paid for the listing

I privately listed a rental property and immediately paid for the listing. They could not verify my husband's particulars even though we are listing the same property with them for the 2nd time. We asked for a refund on the 26th August 2023 after several phone calls from myself after seeing that the property is not listed. They did not bother to give feedback. I have been asking for a refund and I am met with ridiculous demands even though they issued proof that they received the payment.
