Great Yoga Ball But....

I was so excited to receive this ball. I was excited to try a new style ball that could help me with different positional techniques. However, when I received the item, I was quickly disappointed. The box looked just as pictured but the item inside the box was not correct. They sent me a standard round yoga ball. I contacted the seller and they said I needed to contact amazon since that’s where I purchased it. I contacted Amazon and they basically said there wasn’t anything they could do to get me a new one at the price I paid before since the item was incorrect. I cut my losses and haven’t ordered or received the peanut ball.
