Iphone 12 mini - Flipkart was cancelled Iphone return request automatically after of the actual return request rais

Flipkart was cancelled Iphone **mini return request automatically after *days of the actual return request raised. And now tomorrow is last date to expire return policy.
They played mind game very well.
They gave * days return/replacement policy and I raised return request *nd day after I received the product but there is no action from their end no call, no email, no message nothing.. they are doing time pass until the customer return policy period completed.
