sir/madam;
i have brought a new model samsung mobile model is S5233A and its touch pad now doesnt work.when i went to the service station in bhubaneswar, bapuji nagar .their manager told it will take a week to get repaired, i waited for a week then went again.then he said it is still pending.he told the toucpad will come from kolkata, and will take 8-9 days more.then i thought they will make it.bt after 9 days i again went, then one new worker talked with the area manager.and told 5 days more, when i told i cat wait anymore .because the phone was purchased 1 month ago.then the worker said i[censored] will not get on the 27 july then he will exchange and will give a new phone..so sir its my request to you to kindly take action on SAMSUNG SMART SERVICES, BAPUJI NAGAR, PHONE NO :[protected], MOBILE:[protected].
