I had purchased a SAMSUNG mobile phone(Model No. E 2130) from NU-YORK, 1, R.N.Mukherjee Rd., Kolkata-700001 on 05.05.2010. On 18.11.2010, the display of the mobile suddenly started blinking, On the next day, i.e. on 19.11.2010, I went to KARUNA MANAGEMENT SERVICES PVT. LTD., Authorised Samsung Service Centre, Meridian Plaza I, 207, C.R. Avenue, 2nd Floor, Kolkata- 700006 for repairing the same as the warranty period exists. ( Sl No. RD92295915H, IMEI/RSN No. - 358125032021811) I have deposited my mobile but without any information about the type of fault as no engineers were available at that time. After several contacts, I have made over the telephone, on 23.11.2010, I was told that the problem is in the mother board and the mother board is required to be changed.Though I have given two mobile nos. ( open for 24 hours a day), the service centre did not bother to inform about the whereabouts of the mobile. During the period from 24.11.2010 to 10.12.2010, me & my wife had contacted several times over the phone and were told that no new mother board of the model was available.On 11.12.2010, I have contacted the service centre no.(1800110011) and was told to contact with Ms. Sampa Sarkar, Manager of the Service Centre.I contacted Ms. Sarkar over the phone soon and was told to receive the mobile on the same day, i.e. on 11.12.2-10 after 5.30 pm. I went to the service centre and informed about my discussion with Ms. Sarkar.Ms. Sarkar was not in the office at that time and I was told that I would receive the mobile only on next wednesday. When I argued, I was told to wait for half an hour. I got the delivery at 7.00 P.M. when doors of the service centre were about to shut down.I had requested a person of the centre to enter my sim card in the mobile and he did so. At that time, the problem was not there.Today, i.e., on 12.12.2010 at around 1.00 P.M., the mobile started blinking again.Soon, I contacted the service centre over the phone and was told that after first service this type of fault occurs often. I was also told that this type problem is very common in E 2130 model. I was told to contract the manager tomorrow.I have purchased the mobile for Rs 2850/- from my hard earned money.What shall I do ?
