[Resolved]  Flipkart — not get invoice of the product

I recently bought moto e4 plus model (15th july) to gift someone. I had high expectations from this model with the kind of configuration it supported as compared to other phones in the market. But phone had started malfunctioning within 20 days. Its touch is not working properly, sim card tray is not detecting the sim, its overheating while charging so much. So in the nutshell phone is total crap and complete wastage of money. I didnt expected this from motorola brand at all.. Though i have using moto g previously. Please replace the defective piece. As nothing is working in this phone.
When i went to serive center with the same they asked me for th invoice.. But flipkart didnt sent me the invoice even. Upon calling flipkart customer care there is no option to talk to some executive directly. Instead they will call u back.
Due to above missing invoice am not able get this phone checked at service center either.
Somehow i got call from flipkart they are saying that they dont have option of sending the invoice either.. What kind of customer support is this from flipkart... Totally disappointed
