Cash Difference on Purchase

Last week the 06/07/2015 I purchased a Raleigh Peak MTB and Helmet Deal for R1199. This week I see it going for R999. The exact same deal I am very disappointed by this because when I asked the salesman if the bike was going to go cheaper he said no it will never go cheaper again it is going to go back for R1499 and never to be repeated again. So I purchased it the salesman also sold me a commuter starter pack which is not meant for the same bike. When I asked him is it going to fit he said yes it is the same brand but however he was wrong. I would like to get a refund of the difference that I paid which is R200.When I called your store I was told sorry there is nothing that can be done. I have been a loyal customer of Makro for years now and this is not the way to be treated just to make sales and be spoken lies to as a customer.
