Bad Service

I have always been an avid supporter of Woolworths, but recent events are slowly making me rethink my support. I purchased food items on click and collect for collection on the 30th December 2020, only to arrive and not even half of my order was delivered to my vehicle and this after a getting a call on my way there that they do not have two items which I swopped out there and then. I there and then advised them that I do not want half of the groceries and they can take it back and ensure that I get a refund. A manager assured me that this would happen. I also called the call centre and advised them about the problem and to ensure that a refund would take place. On the 07 January 2021, I again called the call centre and was told that the refund had not be processed, but she (the consultant) would find out and call me back. Today is the 11th January and here I find myself calling again only to be told the refund has not been processed. Unacceptable service from such a reputable company that sells themselves on quality and service!!!!
