Microwavable Vegetables Off Before Sell By Date

Bought mixed microwavable vegetables on Sat 21st Feb with use by date of 25th Feb. kept refrigerated until Tues 24th Feb and found large portions of broccoli & butternut were very brown and soggy.This is the 2nd such incident already TY and at R34.99 a portion, becomes very expensive. people use WW Foods for quality. Something has gone wrong. Need WW to respond before I will be supporting the vegetable section.
