Checkers60 delivery complaint.

I have been ordering my weekly groceries from Checkers 60 for almost a year now and are starting ro experience challenges now. I did leave a complaint on their provided email address, but no feedback yet. Twice I have ordered and one of the packages arrived opened with an item missing even though it was charged for and shopped according to the app. I just ordered again after the complaint and the eggs that I ordered was not delivered. It was charged and paid for and according to my app should be delivered. Now I have to get ready and go to the shop anyway to get the product as I need it today. It is really aj inconvenience and it is the third time this is happening now in the space of 2 weeks. My account has been credited but it is really an inconvenience and if this persist I would be forced to do my online grocery shopping somewhere else. The quality of the fruit and vegetables delivered is also often substanderd and unusable. Can I kindly have some feedback on these issues as this is really concerning.
