Woolworths Rotten Foods!

On the 4th of September I bought a 6 pack avocado tray at Woolworths Century City only to find out ALL of them were ROTTEN BLACK inside! On the 6th of September I contacted Woolworths via their Twitter inbox, I was asked to give a whole list of information i.e. the barcode, branch, dates, best before date etc I gave all this information and was told my query is being handled. Nothing happened I then messaged Woolworths via their website and I was told a R60 voucher was sent to my cell number. I told them I never received any voucher and I paid R68.00 for the avocados not R60. I even sent a picture of the avocados. I had been pulled from pillar to post and treated in such an appalling manner by Woolworths. I have spent so much of my time and money trying to get reimburse for the rotten food they sold to me and my family! I have spoken to about 7 different people trying to get my money back because of their poor quality but to no avail. I even went to their Paddocks branch yesterday, had to tell the story to Devine the manager she told me she would investigate and call me but I doubt this will happen. I phoned their call centre today and was told my matter has been escalated and I will 'receive feedback'. I have always shopped at Woolworths but this experienced has left me with a sour taste in my mouth and makes me want to look for another grocery place for my shopping. Why is this whole thing rocket science? You sell rotten food simply reimburse the customer and apologize but this is clearly not the case with Woolworth's customer service!!
