Incorrect color foundation

I went to Edgars Clearwater a year ago looking for a Estee Lauder foundation and was given a sample of Rich ******, further went back and advised them that this is not a suitable color, this time they gave me a sample of Rich Caramel. This was a year ago. 6 months later went back to Red Square Sandton City where I explained that both these colors are not suitable for me, the lady that assisted me did not offer any other alternative she just point blank said they do not mix colors, went back home and wrote an email to Estee Lauder via their website which to date there is no response. After a few weeks went back to Red Square Sandton because I really wanted this foundation, there I met a lady who managed to convince me that Rich Caramel is my color which I then bought and went home. After using this foundation I was still not happy as it is not suitable. After coming across a post on Estee Lauder’s Instagram page I realized there may be other shades that can suit my skin color. Last week went past Red Square Northgate Mall where I was introduced to a color called Cinnamon. To my surprise after visiting Edgars and Red Square not even one sales lady suggested to try this color on my skin and its actually the perfect color. What kind of people do you employ, rather what kind of training do you take your salespersons to that makes them not to be able to advise accordingly. I am now stuck with a foundation that I paid money for and not satisfied with, as it is not my color and because I have no receipt and the purchase was done months ago I cannot return. Am really appalled at the service (or lack of) provided by both Edcon and Estee Lauder. I really love the foundation but now I must suffer with my own money.
