Samsung Service Center — delay in repair and no follow up

Address:

New Delhi, Delhi

i bought samsung E7 mobile set imei number [protected] on 9th April15, its camera was not working properly, the salesman told us that we could change the phone if any problem occurs within seven working days, we went to Samsung service center Varun Enterprise's at shakarpur, Delhi on 16th April 2015( 5th working day)yet the Manager Mr. Rajneesh refused to provide duo letter and submitted the phone saying that it will be returned within four hours, we have not received any information till now, we are doing all folloups and getting nothing in return except that the parts are not available and today we are trying to contact at that service center and contact number given on job sheet is turned off. This kind of service is pathetic it feels that buying samsung mobile phone was our mistake and we will never advise anyone for samsung mobile for its defective pieces and poor service.
