Did not deliver product, and will not refund me. Ghosts client

Warning: Do not use this company. I am very forgiving and understand people make mistakes. I have given Stefan a chance to remedy the situation. In my first time using Stefan I waited months to get the blinds. I then decided to give him another go. I paid in full in December 2022. He then told me the suppliers had no stock. He has continued to give me this story ever since. 11 April I asked for a refund. He is avoiding paying me. I have followed up many times. I just want my money back and I do not think it will happen. For this reason I do not recommend Top Blinds
