Refusal to sell a laptop to a customer.

at 09:05 I called Computer Manie in brooklyn Mall to ask if they had stock regarding a Lenovo ideapad laptop I wanted to purchase. I was told they had one in stock, onto which i informed them, that i would visit their shop shortly. when I came the temperory manager, JACQUES, helped me and fetched the laptop i requested. i went to fetch an adaptor and wanted to pay. i was then informed that I could not buy that laptop as it was for TAKEALOT!!!!!!. I demanded that I wanted that one and was prepared to pay the full amount in via card immediately as is my right by Consumer services (where my cousin is a manager). WHEN i ASKED FOR THE MANAGER NAME AND INFO i WAS TOLD THAT HE WAS OFF AND i COULD NOT CONTACT HIM AS jACQUES WAS IN CHARGE... I informed him that i shall report this behaviuor on Hello Peter where upon i was told that I am rude. they refused to sell me the product in store and said they could eliver one to me on Monday. I relented but then was told I am rude end they refused to sell the laptop and adaptor cable to me!. how can a cash full amount customer be treated like this. this shop owes me the money I had to pay for parking as well as my fuel money as i drove 14 km to go buy a product i was assured was available.
