Hifi corporation bad service

I went the to laybe a Samsung phone which was on special . The salesman told me that I can't laybe today because the person who does laybe is absent so I will have to come back tomorrow and the price will be up tomorrow so I will have to buy it with an increased price. I told him I want to laybe it today why must I pay a different price and he had this bad attitude and he said I must come back tomorrow. I went to report to the store manager after. I think the name of the sales person is Maffy or mafika
