Bad customer service, irritable ground staff.

On the ***5 I laybyed a bed to the value of R3799 over 3 months. When placing the laybye I was told delivery will be included for free. The final payment was due ***6 and when i went to settle the payment I was told that the bed was now R4200 and that was the price I were to pay if i wanted the bed, also with so much annoyance she said whoever did the laybye was a trainee with no supervisor might I add was suppose to explain this to me. When I told the cashier I'd like my money back she said that would be a problem and I have to return when they have money but to avoid all this I might as well pay the difference or take other goods to this value to avoid the inconvenience since they have no money in the tills and when i asked for a direct deposit she straight out said no asked her if the value of the bed dropped would I the pay the dropped price she rolled her eyes and said no i would pay the price I initially bought it for. Both the system and my receipts show that I purchased the bed for R3799 but they wouldn't give me that and delivery was excluded. I am extremely unhappy with this store and will never return.
