Motorola — Device problem - Unknown numbers shows for all incoming call

Address:

Gurgaon, Haryana

Team, i have purchased Moto G 2nd Gen phone last month and start using this phone from this month. After few days device didnt show any contact name for incoming calls it shows only "Unknown Number". I called customer care and they advised me how to reset the problem however the problem didnt get resolved then they told me to you need to visit the customer care center and they will update the phone through system. I called the center and they told me to bring the phone here and it will take appx. 2 hours to resolve the problem. Today, i visited the center(B2X - 122001 Gurgaon) and they just created the job sheet and asked that it will be repaired by Monday. They even dont try to check the problem. I request them to please check and look out the problem might be it will be resolved within an hour however they just refused to check the set and stated that today's set will be checked next day or day after tomorrow. The response given by the executive was so pathetic and they didnt even bothered about customer problem. I hope you can understand my problem and provide a solution.
