Disappointment

I bought sweat shirts at the Woolworths and surprisingly after 1 wash the sweater turned cream Ive been shopping at Woolworths for Over 15 years and not sure if their standards have changed I have been trying to call the store before I go in but no one has gotten back to me been 3 weeks I am very disappointed not happy because they not cheap so I as a loyal customer expect good quality for the money I spend there..My name is Fatima and if one day you decide to get back to me you can call me on ***
