No deliver made and refusing to give me my refund

I have bought a set of chairs and table from Jaymarts, in January, how ever upon delivery I was not happy with the color, I spoke to him and said he will exchange them if he gets a customer willing to buy the color I had. After couple of days, he called and told me that his delivery would be coming to collect the set as mine are still being done, I had to pay for delivery again it was around late January 2025, to date I haven't received anything, I have been calling every week I will be told 'next Monday the delivery will come, I have now asked for a refund which they are not coming to the party. I am busy getting text messages of people acting like they are investigating him and gathering a database of the people he is owing, which I think it's their tactic to delay paying my refund. Don't buy from them , they reap people their hard earned money 💯
