Poor service from Checkers Sixty60

I ordered groceries and vegetables from Checkers Sixty60 at the Ridge at Shallcross on Sunday 28 Feb 21. The goods were delivered on Monday 1st March 21 at 9 am. One item (Futurelife Cereal) was not in the items delivered. Two other items, a pack of papaya and a 600gr pack of green beans were showing signs of rot and decay. I made 5 calls on Monday as well as on Tuesday to the store at Shallcross at different times to get redress. No one was able to help me. The operator indicated that the manager would call back each time I had called, but he never contacted me. Photographs of the damaged goods were sent via email to the Head Office of Sixty60. To date (5 Mar 21), there has been nil response. Usually, the service rendered is excellent. We have been doing several orders on the Sixty60 site over the previous months and have been satisfied with their service.
