Flipkart - executive is very rude on call and not helping

Placed a request for refund of the amount as the product is not as suitable.
Shoes – size small and not getting fit as per expectation.
Carvan – Speaker volume too low and can’t hear even in silence. Also, AUX cable is not provided in the box.
However, Flipkart is calling me again and again and asking me illogical questions like have you reset the device. Tell me how reset will increase the volume of the device. The executive is very rude on call and not helping. Please get the items picked and the amount refunded asap
