Massive price increase.

An hour ago I contacted Decathlon Centurion, as I wanted to purchase a trampoline. I spoke to Jayson. I asked for the price of a Doximyo 365 trampoline. He said that it is R4299.00. I asked if they had stock. He then told me to hold on and came back to me saying that there was a price increase, and it is now R5999.00. This is a price increase of 39.54%!!!!!! How is this even possible?
