Reliance Digital — No more replacement now want refund

I had order a bajaj air cooler on 15 of june.. That's wen all my problem started.
They delivered me the faulty product very next day and it's such a fraud company tht incn even describe in words. Its been 20 days almost i'm still left with tht faulty defective product iny house despite complaining calling for replacement 100s of time.. They don't even lodge a compliant. Once i discussed the issue with someone from. Ecom department lalit kiran... He also lied that you'll get your response within 12 hours. I have no trust in you guys now. I. Want my money back. Had already spend money over repairing of this cooler, the pipe wasn't connected.
After calling the service centre for so many times... I called the mechanic and get it done.. Besides that i'm not satisfied with the product and almost done with your ignorant service. Sp want my refund as soon as possible. You guys are disgusting.
