Pick n pay clothing Seadoon

So today I went in store found a nice pair of shoes size 6 in my size with no tag on Size 7 and 4 have a tag on (same place at the bottom of the shelf) When I took those to the till I was told it's old and new stock Okay how is that possible if it looks the same ? All 3 pairs was at the bottom at the back of the shop by all the mark down things I waited long for a manager when I got the manager and I explained and showed she insisted it's not the same price I stated my points how its makes no sense I phoned customer care who completely ignored my point and did nothing about this even after telling them I will be posting it on social media as I have taken photos of this items .... customer care and the teller aswell as the manager have really disappointed me on this one ! Please pick n pay make sure your tags are on especially when items are on the mark down shelves!!! A waist of 45 min of my life! This was at pick n pay clothing seadoon They didn't even ask to email them the photos of the items so customer care can look into this.
