False advertising

On 29 February 2016 I went to woolworths cosmetic section to purchase yvesrocher pure system daily exfoliating cleanser.i noticed there was a price list.when I checked the product I was buying was listed as 150 ml for R110.whereas the actual tube is 125ml for R110 same as 150 ml.when I enquired i was told by Alice that they will do the investigation and revert back to me the following day 1 March 2016 but that never happened
