Misleading the clients with the prices.

On the 15th of this months I placed order on MyRunaway and I received order confirmation, estimated delivery date is 17-23/01/2025. On the 16th during the day they sent me email saying there was an error on pricing so they want to cancell my order and they will refund me. I rep**** to them saying that pricing error is non of my business, i saw items with the prices and liked them thus why I placed order, customer pays what customer see. So I saw that price thus why I placed order. Today I sent another email since status of my order is closed and email not rep****. Then they rep**** telling me that it was not system glitch it was human error on pricing, so they can not send my order as they will loose and aslo affect their business.

As a customer how do I know that the price is right or wrong?
