Apple India — Unable to install applications on Iphone 13

Address: Hyderabad

First of all I am an first time user of Apple Phone. Bought Iphone13 for 75000 rupees on 2nd May 2022 and from the very next day I started using the Iphone13 but was unable to install any applications. So I started complaining to customer care from then( means 2nd May 2022 to till date(24th May 2022), literally I had wasted 23 days of time to resolution for this issue and there was no proper response, explaining every day about my issue and no resolution yet. Its a completely waste of time .I need my money back and take your IPhone13 back that's it. I am fed up with all the calls and wasting my time daily.
