Bad service and false adverti*****t

I went to Woolworths Canterbury 3148 on the 5th of September 2018 to purchase the Veggie combo for R125 which clearly state you choose any 4 from their list and the kilograms however the kilograms advertised were not there for example the sweet potato was advertised as 3kg and they had 2kg as well as the butternut it was advertised as 4kg but they had 3kg which is false adverti*****t and when i query this at the store i was told to call the head office as they do not make the pricing by Thuli who was the manager at the store she then override the 1kg for sweet potato but still the butternut was 3kg instead of 4kg.
