Customer Service????????????

Went into Ackermans store at East Rand Mall, saw an item that I like..... checked and no size, asked the cashier if they could please check on the system whether they can find the right size for me? Went to Manager, came back and said that cannot check as it is old stock?????? REALLY??????????????? Went into another store and they also had a few, not the size that I wanted though...so, would it really have been such a mission to check for a size on the system???

Details of item as follows:-
