Bad attitude and service

Rage store in carletonville mall the service was very bad and the lady who was assisting us was very rude I don't know if she is the store manager or what we had to wait more than 15 minutes to be assisted while she was busy training another stuff member on the till , were we supposed to pay ,when we complained she told us she won't help next time when we visit the store . How can they be training in each other when the store is busy . With people on the cue , our time can't be wasted because of their convenience, we also have other obligations. To top it all with the bad attitude they gave us .
