Bad Customer Service

I went to Jet Highveld Mall to purchase a Baby shower gift on the 25 September 2015,the was a long queue only 1 cashier working, and the way it saw it he was clueless about what he was doing because it took him close to 30 minutes to assist 1 customer, I then asked him to get assistance because it was a mount end Friday and queue was long he just looked at me as if I was crazy and the was a guy that was working next to him in a cell phone department gave me a bad look as if I killed somebody, everyone was now complaining about the slow service we are getting and we asked him to call a manager on shift he/she refused to come and explain to us whether they don't have enough staff or the systems are slow or what, I mean really Jet??Is that the service you give your customer's??I will never go there ever again actually I don't go there because of the slow and unprofessional service they give, next time please add more till operator's especially in a mount end weekend we don't have the whole day, I ended up leaving what I bought and went to Baby Boom I didn't stand even 5 minutes there the service was quick goodbye JET you have lost a customer, never again!!!
