C***** lies

I’m totally disgusted to know we buy these products daily and yet we are **** too. This is the second time I am having an issue with c*****s so called extended shelf life 2lt fresh milk. This milk had an expiry date of the 29th December 2020 and has been sealed and kept in my fridge today I opened it to use it and guess what it’s spilt and sour ... this is the second time I had to throw my money down the drain and I don’t think I will ever want to purchase this milk again . How can something have extended shelf life but go off before the expiry date has even passed !!!!! Totally upset I expect c***** to do something about this as the first time I let it be now I won’t !!!!!
