Cajee cycles (shoe booties)

I went to Cajee Cycles last week Saturday (2022/06/04) to purchase Louis Garneau cycle shoe booties. Cajees did not have any in stock and I was told that they will get the stock. I was quoted R425.00 by the Manager of the store due to the fact that I could get them at R450.00 from another supplier. I was also told that I will have them by Sunday (2022/06/05) before the store close at 1pm and they will call me to collect. After numerous calls on Monday, Tuesday I was eventually called on Wednesday that the stock arrive. This is when the shock came. All of a sudden the cost to me was going to be R550.00. This is R125.00 more than I was quoted. When I told the salesman what I was quoted on Saturday, the attitude was, R550.00 is the best price I could do so take it or leave it. So how come the manager was able to confirm a price of R425.00 on Saturday, and on Wednesday the price went up to R550.00. This is absolutely crazy. Cajees need to stick to the price that was quoted when stock arrive.
