BarnFires - Never use them

After procuring a Fireplace from LAVA Fires, Pete from BarnFires Project was recommended to come and install in May 2020. After the first rains hit last week (05/10/20) the water came pouring through ruining my ceiling. Pete had not sealed the chimney/flu or if he had, it was a terrible job. Upon calling him, he asked for location which I gave. I asked him to reseal and paint (not replace) my ceiling to which he frivolously declined the painting. Wanting the sealing done before further rains came, I left the argument to paint and asked when he would come and reseal - his comment - "When I am next in the area!" I requested he come ASAP (I would have accepted a few days) otherwise I would take to HelloPeter/Lawyer and LAVA. His response "What is your problem Steve" I offered him the opportunity to come and seal again before following the above steps and needless to say, its one week later, he has blocked me on WhatsApp and refusing to respond to my SMS. Worse, he has created a fire hazard by installing incorrect flu with no insulation going through a wooden ceiling. This has forced me to sub contract another installer and having to buy another piece of piping with insulations, pay to re-install and fix my ceiling. Do NOT touch BarnFires/Peter - his workmanship is shocking and his attitude/service is even worse. This is not a "He said I said" dispute - I have everything in writing and photos.
