Sony India — Sony Xperia C3 dual sim mobile is giving me constant trouble

Address:

New Delhi, Delhi

I had purchased a Sony Xperia C3 Dual Sim Phone on 08/02/2015 from Globalit Life Style Technology Store Pvt. Ltd. (Future Forward) Lajpat Nagar, New Delhi via Invoice No. SILJPT23286 and customer PO No. INSO521425. The phone is troubling me since last one month. It gets switched off, hangs, the voice cracks, the power button doesn't function properly and a lot more. I had visited your service centre at E- 17 Lajpat Nagar and got the 'software updated' as the service centre had prescribed. It's not even two days and the phone is troubling me again. I was speaking to one of my contacts in the evening and the phone got switched-off on its own. It's not opening since 6 PM today even when I tried to switch it on almost 10-12 times. Please help me out. Please replace this phone and provide me with a new phone, even if its of same make. I don't expect such 'deficiency in service' from SONY as its a well known, accepted and international brand. Kindly provide me with a relief and be upto the standards of a good customer satisfaction company. I look forward to hear from you soon. Please Please Help Me OUT on Priority..
