Shoprite Vanderbijlpark False advertising

Went to purchase 5kgs chicken which has been advertised online by their website for R129 on the 10th September 2020, how ever I was informed that the promo wasn't for that particular store( Believe me, the ad didn't mention which stores is that promo valid from)... Saying that it was already in the afternoon I just paid and left only to find out that I actually paid R159 for the 5kg chicken pack. False advertising and very misleading.
