Bad service

Hi<br> I bought long life milk on 17/02/2015 from Woolworths, opened it on 19/02/2015 the evening and put it in the fridge and the 20/02/2015 it was sour.<br> Best before 26/07/2015.<br> I have waited since February month for a reply from Woolworths and this is really pathetic that I have to wait so long for a reply. My Ref ***.<br> <br> Very disappointed!!!!! <br>
