Bad colour Foundation - waste of monies

None of their foundation colour codes match up! I am currently struggling to get stock of the Candid range of foundation in Sand Beige code 220. A few months ago I also struggled to get the Candid range in this colour and so I bought Sand Beige in expensive Age Defying glass bottle which colour is too dark and has different code range from the Candid, code25. Waste of my monies! Then today again no Candid in Sand Beige in stock so I now bought the Colourstay FULL cover in Sand Beige but the code was 210 and once again TOO DARK. Very expensive to not stick to the same colour.
