Review of Checkers:Checkline FreeCall

I purchased olive oil at checkers New park (Kimberley. Only to find out that my pregnant girlriend saw that the oil has expired on the ********....whereas I bought the oil on the 29th of October 2016. For such a huge company in Africa we get to be sold expired stock, now i can see how they manage to get such a huge turnover every year out selling people crap. Now my question is what is going to happen? Is this matter just going to be left unattend.. I want answers I want action to be taken because I am surely not going to let this one go....we go to that store trusting that we will get proper goods not to double check expiry dates on each and every item we want to purchase. Is that how you run your business. I still have the tillslip and the product purchased...
