Sixty60 items billed but not received

I have placed an order online on 8/04/2020 and delivery and billing was done the same day. Shortly after receiving my goods, I have logged an issue on 8/04/2020, followed by an e-mail on 9/04/2020 about items billed but not received yet.

I have phoned Checkers at Willow Bridge on 13/04/2020 for assistance on my issue. They indicated that they will investigate and phone me back. Up to now, 16/04/2020, no phone call or any feedback received on the issue yet.
