Wrong price

On the 27th of December 2017 i visited Musica at Brits Mall. I bought a Cd and want to buy JBL headphones that was priced for R169.95. When i get so the pay point the JBL headphones is now R1699.95 when i confronted the cashier she said the pricing was a mistake and can not sell it to me for that price. Luckily i took photo's. I contacted Musica's head office on Monday the 07th of January 2018 and no response since.
