False adverting and appalling customer service

Woolworths advertised \Buy 2 get 20% off\" but when I purchased the 2 racks of lamb on promotion I checked my bill and saw that I received 10% off only. The supervisor then told me that 10% off 1st item and 10% off 2nd item is 20%. When I tried to explain that is only 10% off for buying two items the department manager Ricardo Walters said he understood my view but that 10% off 1st item and 10% off 2nd item is 20% off the total purchase, He took my details and said he would get back to me which never happened.<br> <br> I then tweeted a picture of the promotion and Woolworths asked for my details etc. Four weeks later and I had a call on Tuesday evening from customer services who repeated 10% off 1st item and 10% off 2nd item is 20% the total purchase. I was then asked about original receipts and I advised them to look at my Woolworths account to which the response was that they would not be able to do anything without an original receipt (which I do have).<br> <br> Woolworths staff clearly need some help with basic maths and learn about customer service as this shows a total lack of care and follow through.<br> <br> Misleading adverting and extremely disappointing customer service"
