Waiting for Response from Ackermans as not honouring price on the Tag

So me and a friend of mine went to one of the Store's the one in Claremont, when we got there I saw some shorts which were priced R11.90 and I thought to my self "WOW" what a bargain so I decide to get me 2 of those shorts. Then I went to pay and cashier tells me no the item is R119.00 but I'm like no the tag states it's R11.90 which we then request for a Manager to come assist in this matter, she comes and tells me then same thing I then ask her what's on the Tag? Which she then replies it's R119.00 and asks if I'm taking the items or not but because I really wanted these items I take them and tell them i will be taking this further as I also take screenshots of the price on the shorts and still have the slip. I uploaded the pics on Ackermans page on Facebook explaining my matter so they requested for my mobile number and I inboxed it to them as they say they will escalate the matter and get back to me, that was on the 4th of Jan and I'm still waiting for response and nothing yet from them. I'm sooo disappointed in Ackermans and it's management.
