Nokia India — nokia 6.1

My name is vishnu mohan, one week before i bought your new model nokia 6.1 from reliance mobile store fathima nagar pune (Pin:411040).
The performance of the phone was very very poor it doesn't have a good battery backup, it always hang i don't know what software it is... I'm hearing ad feeling this first time just after one week it is hanging...
You people are advertising on zeiss camera... Ad quality... It's also very poor when we click a photo it will show the pic was taken by when we take it back... The pictures is not their, what i want to say is it's delaying for 5-6sec, poor performance by nokia team ad software technicians, i personally never tell any one to buy nokia mob because of poor performance.
Tell me how can i sort my problem, tell me the solutions, because i spend 16999 rupees for this rubbish peace of mobile.
Nokia team break our trust on nokia.
