Urban Company — Chimney Service cheating

I had booked a chimney service on 3rd nov and technician named Veeresh visited. Ext day. He checked and told the board needs replacement and took away chimney. Next day he came back with chimney and fixed, I asked where is the old board, he have no answer. That made me doubt that he didn’t change it. When he left I opened the box and checked, it was my old board he just fixed facing other way. He charged around 3k just rotating the board other side. Contacted service desk many times and looks like technician is ignoring them as well and they keep postponing. I am not going to use this Urban company in my lifetime. They are indirectly getting profit of this kind of cheating,
