Missing items again

I mainly order my groceries from checkers since ir is convenient. For my past two orders I did not receive al my products. Every time it seems like one whole bag is not delivered. Crediting my account is appreciated but now I need to get into my car and go to the shop and physically buy it. This is not on. If this continues I will not order from Checkers again and rather support a business that does deliver all my products ordered and paid for.
