Saravana Stores — worst kind of service

Bought berow for 12k along with other products worth 60k on 6th jan in padi furniture shop & they delivered it on 11th. Berow wasn't good one, i have been telling them to repair or exchange since 12th but they not even response for my complaints. Don't u guys check the products before delivering it to the consumers. I called to the manager & he said service person will come to repair but that guy not even picking my call what a poor kind of service. Without the good quality & service how come the customer will visit again. I[censored] r not ready to give service then better refund the amt so that we will buy the products in some other best shop
