Apple India — misleading by customer care for phone heating problem

Address: Kanpur, Uttar Pradesh, 208025

Sir

I have gone 3 to 4 times to apple service centre for phone heating issue in last 8 months but every time my phone is just formatted & given back to me.
Since several reoccurrence of same problem permanent solution is not given & warranty of my phone is also going to be expire.
Pls provide a solution for that.
Phone should be replaced in place of this rubbish phone
