Broken pressure cooker

I purchased a pressure cooker which arrived already bumped/damaged when I opened the package. I immediately returned the item in the same condition it was received. To my absolute disappointment, the item was sent back to me exactly the same way, still damaged and not even wrapped properly. This shows a complete lack of care, quality control, and respect for the customer. At this point, I am extremely annoyed and frustrated. I no longer want an exchange. I want a full refund immediately. I should not be inconvenienced further for a fault that was not mine to begin with. This experience has been very disappointing and far below acceptable customer service standards.
