Disappointed Pick n pay customer

Went to pick 'n pay Lifestyle Centurion. Advert on the shelf read "Any 2 Comfort Concentrated Fabric Conditioner Assorted 800ml for R75" that is all that was on the advert. When I got to the Till I was charged R59.00 for each. When I queried with supervisor and floor manager Bongani Mathebula I was told a certain range is excluded. I mentioned that the advert does not mention that a certain range is excluded and only mentions "Any 2 Comfort Concentrated Fabric Conditioner Assorted 800ml for R75" therefore I took any two that have the same description as per the advert "Comfort Concentrated Fabric Conditioner 800ml" but they refused to give me the product s at the advertised price. When I asked them for their escalation process or manager details as I would like to escalate it further I was told to contact customer care. They refused to acknowledge that the advert on the shelf was misleading and failed to mention that a certain range is excluded.
