Disappointed at Checkers liquor double standards

Checkers Hyper Liquor is advertising 24 Savannas for R250, I thought Checkers Liquor and Checkers Hyper Liquor were one and the same but not so, Checkers Liquor charged me R299. 99for 24 Savannas and I only realised that after I paid and left the store. The manager at Gezina Pretoria would not refund me after explaining that they are not one and the same do I paid R49.99 more per 24 and I bought 3 cases! I am so totally disgusted, they will never see me again.
