Samsung Mobile — Samsung mobile a7 display issues

Address:

Thane, Maharashtra, 400601

Dear sir / Madam,
I have bought Samsung galaxy A7 in the month of June 2015 after using for six months it's started giving problems like slow function, getting hang & display issues. I had been to Raj teleservices Mulund service center and complaint about the phone and they have rectified the same by changing LED panel of handset and ensured me that the problem has been rectified but after a week again the handset was having display issues. Hence again I had been to same service center and complaint, this time they had done some checking at their end and rectified the issues. This rectification did not last even for a week and same problem starting troubling me.
This time I went to same service centre and requested to replace the handset but they have denied and upgraded the handset with latest software stating your handset will not have any problem now.

I am sorry to say this problem not rectified so far as my phone display keeps blinking and I need to reset the phone every now and then.

I want some senior person to look into this and take corrective steps to avoid major escalation.

Warm regards,
Ajay Shetty
