Incorrect pricing and client must pay.

I bought a hard drive for R299 as priced. I received an mail said that it was priced incorrectly and I will be refunded. I dont want a refund, I want my hard drive! I paid what was asked, its not my responsibility to do pricing its yours. I will be going to sosial media, Hello peter and consumers council until I get my paid for hard drive, I bought it for a reason and still expect delivery on the 5th Takealot How is clients now suppose to take or leave the refund for something that was advertised incorrectly?
