Nokia India — refused to replace manufacturing defect nokia 8 mobile phone

Address:	Hyderabad, Telangana, 500034
Website:	www.nokia.com

I have purchased on 16th July and i found its manufacturing defective from day 1 but due to lack of identification i delayed informing.

On 06 August i gave it to service center(Delight Solutions, Hyderabad with Job ID 180806/003 ) & they asked to replace display and asked max time is 14 days. now its crossed more than 25 days but they are not responding my emails and if i call they don't know when they will receive display and asking me to wait 2 weeks more.

I used 12days but its been in service center from one month.
i want replacement or refund
