Motorola Solutions — Moto g (3rd generation) problem

[IMEI/Serial No: [protected] which was purchased on[protected] . Since the day one I am facing lot of problem in this set and various mails & communications were made to you & to your service center in this respect.
After every 2 months I have to visit service center of Noida Inline images 1M/s Vanshika Electronics, G-7 & 8 Ground Floor, Dharampali Place, Bhoj Mkt, Behind Vinayak Hospital, Noida-201301 as my Mobile set gets hanged & i am not able to receive & make any calls .Even some functions would not work on this. I must have visited your service center for this problem at least 7 to 8 times in last 1 year with this problem only ( can be verified from service center also copied in mail ) & above refereed service center would format the Mobile & again this would work for at least 1 to 2 months without any problem.
Now again same problem has happened & when I went to service center they reported that since Mobile is our of warranty & I need to pay for the formatting of this set. this is a problem with this mobile from day One & in fact i should call it manufacturing problem but still i am keeping this mobile but to pay charges time & again for the same problem is not possible for a set which has inerrant problem.
