Samsung Service Center — malfunction of mobile phone by authorised service centre

Sir, Since I experienced a low battery back up on my Samsung mobile (GT – N 7100 Bearing Sl No RFID12DGPFB, RSN NO [protected]Note II ), I found some of the built in applications are running in the back ground, which drains the battery faster. As I could not rectify it, I had given my Mobile (Note II) to the Authorized Samsung Repairing centre on 11 Apr 2015 at Kavil Kadavu, Kodungallur, Trichur, Kerala (Ph No[protected], Mob No. [protected])for its rectification. They have issued a manual work order sheet bearing No. 11302 regarding the receipt of mobile. So far the complaints have not been rectified. It has already been elapsed more than three weeks time for the rectification of mobile. The authorized service centre agents are repeatedly giving some excuses like they are on job, checking the item etc etc. Earlier they informed that there is a short on mobile and followed by IC problem and now they may tell the entire board to be replaced. When I approached the Samsung Customer Care they asked about the JOB Sheet Number which is supposed to be generated by the authorized service centre at the time of receiving the item. But the service center has not been generated any job sheet where as they have given only a manual work order by which the service center is hiding the work details from the Samsung Company. According to Samsung customer care requirement, when I contacted the service centre, they have given a Job sheet No [protected] without any date. But it has been generated after two weeks time As far as I am concerned, it shows the deployment o[censored]nexperienced and unskilled personnel to undertake the service, which results a simple work to complication. I am sure that service center couldn’t pin-point the actual fault and giving some flimsy reasons to justify their try and error method. On 05 May 2015 when I visited the service center I found the entire mobile has been changed. They have shown a mobile with a front panel scratched on many places. I hope they have even changed the panel it self by which I couldn’t identify my mobile and it is not understood what they have done on the major components Your kind attention is invited to persue the matter physically through a well experienced technician at an early date and a detailed work report may please be obtained from the agency from 13 Apr 2015 to till date regarding the service of my mobile. The follow up report may please be intimated.
