I have submitted the faulty htc 830 handset (In warranty period) in near by service center on 07.03.2018. But till now the issue is not resolved. It's already 20days over. I am not getting any fruitfull response from the service center. I will lodge a case in consumer court if i am not getting the product in 2days. I want to inform you that this product is purchased for an ipos officer for official use.
