Woolworths misleading online shopping pricing shown low

Woolworths online ordering website prejudices the customer. Customer must pre-select the size, then colour. (Heat generation spencer) However, once customer wants to look at another colour; coincidentally named "medium beige", the online page defaults to XS size again. Customer reads "medium beige" and that is the size she ordered. Woolworth claim you have to each time click size, if you change colour. This resulted in a R50 loss per item purchased, and Woolworths claim that the customer is at fault, as customer has to keep entering size everytime a colour change is selected. Medium beige is misleading, as customer chose medium in size, but chose size then colour, not colour then size, and got a price of R160, not R210.
