Misleading adverti*****t my checkers 60

I'm rather frustrated by the response I received from Checkers.

They advertised 2 x 900g lancewood cheese for R129 when I queried about the items I got a response from Dylan disregarding the advertising and highlights the grams on the cheese packaging and tells me I'm reading it incorrectly yet the price and 900g are advertised on the special!!! Why is this my problem when checkers is advertising incorrectly?????? I am now insulted by their staff for the error the team caused.
