Missing customer service?????

Wish I could give less than 1 Star (maby hellopeter could look into that) lodge a query with the oh so (not) helpful call centre agent on the 15th of November regarding my cash back miles not pulling through to my banking app. Eventually received an email saying your cash back is paid out in miles. Not what I asked. Spoke to a manager , Sheldon, on Friday 6 December (yes you read that right) who said he would personally speak to the relevant teams on Monday 9 December and get my query resolved. He would then phone me back with feedback. Guess what... still not resolved and no feedback from Sheldon. Clearly, not a man of man of his word. Disgusting service. You should be ashamed.
