Cant get a simple answer

Ive just had the worst experience at pick n pay comaro crossing. Regardless of the situation at hand, all I wanted was a simple confirmation that all was corresponding on my smart shopper card because the store was offline and I had just redeemed my points. The supervisor, who claimed to be Margeret but refused to tell me much more than that treated me with a childlike condescending manner and even had the cheek to laugh at me as opposed to giving me much needed pacification that I indeed had not lost nor forfitted my ppoints for future use. I am disgusted and appalled that I was made to feel stupid, uncomfortable and cherry on the cake, laughed at. How is this acceptable practise in stores. Not one manager approached the scene and im still no wiser that I have not lost money due to systems being offline!
