Consumer Redressal

My Samsung grand 2 phone has been in defect from the time I bought it.I purchased it on 27 April 2014and with a weeks time it got into repair mode.The mother board got changed and you can check out the following attached email.The amount of inconvenience I faced moving from one customer care center to another and then finally mother board got changed after weeks time.Again after 4 months the same problem has arisen.Now whether samsung will follow the same process of repair and wants the consumer to visit the service centre again and again.No Use at all. Called samsung service center this morning but the senior operator was not available,kept me in waiting for long time and call got discontinued.No importance given to customers.Pathetic service and poor product.Totally fed up with Samsung.Lot of time,money and energy wasted. Request you guys to help me to get a replacement asap.
