Flipkart — received faulty xiaomi note 7 pro

Address:

Banashankari, Bangalore, Karnataka, 560078

Respected sir /madam,
I had ordered my xiaomi redmi note7 pro (Neptune blue, 128 gb) (6 gb ram (Order received date was 11th october 2019) from flipkart, this mobile does not detect the network, initially it worked for a week, then only single network gets activated at a time, and the internet does not work at all, when the same sim cards are inserted to other mobile, it works absolutely fine. I called to the customer service and complained about the matter, they said it cannot be exchanged as the exchange time period is over. And they asked me to go to the xiaomi service centre. I have given the mobile to kamakya banshankari service centre for repair, they replaced the mother board, it worked fine just for a month. Again the mobile was taken for repair, the software was updated and given, it seemed to work for 15 mins, after i returned home, its still the same issue.

I am really not happy with the faulty device received from flipkart, i am missing most of the important calls after i started using this mobile. Really disappointed, i need help here. Order no. - od[protected]

Thanks,
Anitha
