Urban Company — Warranty fraud

After a detailed consultation with UC, I availed painting service. Consultant promised about 1 year warranty for cracks on the wall. However, there is no written confirmation. After I took the service, they denied warranty for the same. I have been requesting for callback and sent multiple emails regarding this to UC customer service. Nobody bothers to respond. They have cheated the customer regarding warranty just to take the service. Once the service is over, they don't bother to give a callback. This is the reason why they don't have customer service number in india
