Poor Woolworths Customer Service and Produce

Had purchased a box of Satsumas from Woolworths Bassonia on the 17th of April, got home found a few rotting / moulding items in the box, was too late to go back to store. Have sent multiple emails to Customer Service since then with ZERO response. With the price we pay for Woolworths products there should be a certain level of customer service expected. It is now almost a week later and still nothing, only way to get results is by changing retailers.
