Woolies you are the weakest link goodbye

I have dealt with this organisation for most of my 50+ years that I have been around and by far the majority of my interactions with Woolies is of a positive nature , however there is one department which I can only think of which Woolies may have outsourced its function to possibly Escom or S.A.P and I'm not referring to the IT company Sap , and this department should in fact be their shining star but I've just experienced terrible service now for the forth time , where I was promised something with no follow through from their " customer care center" it so happens that I am pretty much destitute and really struggling and my sister helps me with food every month , she does this by going online in Australia and ordering me a voucher so I am able go buy food but once again Woolies haven't delivered and the customer care center told me they would call the driver and get back to me which they of course haven't done and I don't even have the airtime to call them , so I will definitely go hungry tonight and going on past history probably for a few days to come , sorry Woolies but a chain is as strong as its weakest link and your "customer care department " is the weakest link .....Goodbye!!!
