No after sales customer service

I ordered tiles from them and received the full pallet damaged. I sent it back immediately with a note that I swnt it back due to it being broken. I had no response, swnt an email asking for a refund again zero reponse. I have been struggling to get any response from them. I really dont know what to do. I have spent a good amount of money with them this past month and feel dissappointed by the lack of care from customer service.
