Incorrect pricing advertised

Good Day, i have just returned from your East Rand Mall store and had an unfortunate experience there. Nike takkies were marked on the box and multiple pairs of shoes @ R499 on special, all the same one. I go the till to pay and its rings up as R650 (whilst the R499 price tag was still on). Manager comes and says the system says its R650 and she cant do much. I was furious as I was buying it for my son's birthday tomorrow and this was the max budget and I don't have time to shop around for another. I made a fuss there and said i shop according to what's advertised on the item and not what's on the system. In any case i am not sure what they had discussed but i ended up paying R499. I think that a staff member (thembakhosi i think) stepped up and took responsibility when it had nothing to do with him, and that is not on. Tekkie Town as a brand must take responsibility and not one individual. Note - 2 other of our branches have these same tekkies at R499 on special and it rings up R499...so if i find out that this staff member has to be financially accountable.... myself, my family and friends will stop supporting you. This is wrong, period! The teller stepped aside and did not bother in getting involved...but the staff (thembankhosi) member stood up and said he just wants to give good service, and that I applaud. When responding to me, I would like to know how this was resolved please ? thank you
