Rochester Refuses to Deliver A Product I Purchased and Paid For Because "The Price Attached Was Incorrect"

Good day,

I am extremely disappointed with Rochester, and its unprofessionalism. On Sunday morning I searched microwaves on google, and saw a Russel Hobbs microwave on their website. I then created an online account and processed an order and made an EFT payment to finalise the order and delivery. Thereafter, I received an email confirmation of my order indicating that the item will be delivered. In fact, I let go on an another appliance that I could have purchased but instead decided to go for the Rochester product.

On Monday morning I received an emailing letting me know that they won't be delivering the product to me because they mistakenly put the wrong price on their website. Therefore, I must provide them with my banking details so they can process my refund back into my account.

I am not happy at all and very upset. It is not my fault that they acted negligently. The microwave was also an opportunity cost of letting go of another limited product so I can have the microwave. Now they want to tell me stories?
