After the barn Refuse to respond about defective custom table purchased Beacon New York

We had purchased a 10 x 4' oak table from after the barn about 10 months ago taht we absolutely loved. We dealt with Bob the owner who was amazing but unfortunately passed away about 6 months ago. His son Rob has since taken over the business. We had an issue about a month after receiving the table with the wood splitting open the table in a few different areas. We contacted Bob about the issue and he was more then gracious to come by and take a look at the problem. He agreed that the was odd and that the table top would need to be repaired.
Bob had told us he was going to send his crew to pick up the table top from our home on Long Island and bring it back to Beacon NY to correct the issue. Bob followed through like he said and a few weeks later picked up the table and a month after that we had out beautiful table back. 
Unfortunately the same issue occurred within the two months our table returned. In that period of time Bob had passed so out of respect we gave an extra month before we contacted Rob who was now in charge to let him know of the issue. I first reached out to him on February 9th 2017 by Facebook messenger. After a few days Rob responded and told me to give him a call so i did numerous times with no response.
I then proceeded to text him which i had gotten responses from him asking for photos and measurements which i responded right away. Last i was told that Rob was going to build a new top and i would have it in 3-4 weeks. This was on March 29th 2017. Since April 26th which is 4 weeks later i have reached out to Rob and after the barn about 20 times by text, phone, Facebook messenger and email with not one response.
I spent over $4000.00 on for this table and cant believe that this company who makes beautiful furniture has done this to my family. I have given them every opportunity to correct the issue and have been more then patience. I happen to be a small business owner myself and cant believe the treatment i am receiving.
I have attached photos of the table and the conversations with the owner for the public to decide if they want to get caught in this same situation.
