Woolworths customer service no integrity A expired vile chicken

Iv never been so disappointed to say the least of the lack of customers service of Woolworth's staff in vangate , it's been nearly a month since I bought 2 trays of chicken at Woolworths in vangate opon using it the chicken had a vile smell and was brownish green in colour on the one side of the chicken portions I then contacted the store and was advised that they closing in the next 5 minutes I can come to the store the next day which I did the staff member who assisted me was extremely rude off the bat demanding a receipt of purchase which I gave but was abit faded due to it being about damped cause I left it in the bag with the chicken he went on saying that they not able to exchange or refund me without the receipt which I had present he then proceeded to ask if this chicken packs was bought at Woolworths and not another store which to me was ridiculous the 1 pack was still sealed with all the labels on bedsides the pack that was opened I asked to speak to the manager and was said the manager was not in I asked for and assistant manager was said they don't have at this point I was frustrated and so upset the staff member kept telling me they can't assist I need to call customer service and explain the situation after nearly 20 minutes of debating I left and contacted customer service to explain what has transpired I was then advised that they would contact the store and revert back to I waited a couple of days no feedback, I called the store myself to speak to the manager to get a follow up I had to re-explained the situation again and was said they going to follow up I gave the reference number I received since then iv not received a single mail or call.
