Worst customer care ever

For the past 2 days, I have been struggling to get help. Two times I have managed to get ahold of this other lady at the store who was not helpful at all. I asked her about their deals and she tells me she can't tell me over the phone due to security reasons which is nonsense since all the other stores told me everything I needed to know. Today was worse, she answers me partly then leaves me on hold for over 16 minutes which am tired of being on hold. Am not sure what's going on but this is really bad, how can someone not care about helping out clients. This lady needs to be reported for very bad behavior and overall service. V&A waterfront.
