Poor Customer service / store processes

I visited the HI-FI corporation store in Springfield park (Umgeni) to purchase a television on lay-bye. Upon selecting the tv I was given a ticket to and directed to the front of the store to complete the process, only having to get there and there's just 1 PC that was available to conclude the lay-bye application. I waited for almost 45 minutes and when questioned a staff member he advised rudely that's the only pc with a (Sign pad) I told him that it's month end and there is so much staff available yet no one has engaged or persevered to assist me yet all was in small groups chatting, only thereafter was I assisted. Whilst completing the process the barcode of the TV i selected was not going through and i had to then select another TV, thereafter I had to pay a deposit and then the quote / barcode was not going through at POS, i had to wait for another 15 minutes and still nothing. eventually a manual docket was captured. This was a painful experience as I have now spent over an hour in the store just to complete the process. I would not want to go through this experience again. Please come up with Standard operating procedures aligned with customer service engagement and deliverables.
