Business ProfileforRG Design & Build

I ordered an outdoor chair and sectional from *** that was advertised on ******** ***********. I inquired about price, date of completion and specific details about the made to order product. *** informed me it would be 4-5 weeks, 1050$ and 50% is due to start the project. I sent *** 525$ via e-transfer June 20th, 2023. On July 17, I messaged *** to see when the product would be ready for pick up. He replied july 21st, saying it would be another week or two. I then checked his reviews on ******** and to my surprise they were mostly negative for price, communication and completing product in a timely manor. I sent *** another message july 30th, with no reply and another on July 31st explaining that I didn’t feel comfortable that there was no communication or clarity on my product timeline of completion. He then responded it would be another week or two. I explained I was unhappy with the constant “another week or two” and he said he would return my refund, asking me for my email. As a result, he has taken down the original ******** marketplace post, blocked me on ******** and won’t reply to my emails, messages on ********* or ********. He has not returned my deposit, or completed the ordered product. But has kept my money. He is violating his written agreement of completing my order in the 4-5 weeks and has kept my deposit, which is not right. I tried sending him a message saying if he could give me a solid completion date to not go past then I’d be ok to continue and have him build the product but he blocked me.
