No interest in assisting the customer

I needed to change a shoe for my boyfriend and called the Sandton branch on Saturday midday to ask them what time they close. A gentleman answered the phone and advise they close at 6pm. We get to the store around 4.15pm only to find that they have already closed. Anyways we go back on Sunday and he requests for a certain size and the lady says she can find it on the system but she can't find it in the storeroom!!! She didn't even offer to see which other stores could assist us until we asked her and oh boy she was not too impressed. She called Cresta who took forever to look for the shoe. They then told her that there's only 2people in the store and they would call us back when they have time to find the shoe. She then called Rosebank who had the shoe and kept it aside until we got there. A salesman by the name of Abel was really helpful in assisting us with the change of the shoe and things went really smooth at the store. As for Cresta, still no call and as for Sandton I'm quite disgusted!!!
