Checkers Sixty 60 terrible service!

Hi there, I placed an order on Saturday, 28 March on the Checkers Sixty 60 app. I paid extra 15% for replacement products which is not a problem, however, of the 12 items I ordered, I only received 5 items. I tried logging an issue via the app but it was like my profile was deleted and I had to recreate an new profile and my order history was gone. I emailed the *** since Saturday and no one has come back to me about any feedback so that I can be credited for the missing items. I understand you’re busy with lockdown, but you shouldn’t (especially now) lack on customer service. I complained on Checkers Facebook page and still no one contacted me. This is day light ******* and it’s unacceptable!
