Bad communication froom onedealaday. Bad comms channel and bad service.

I am usually very happy with their service, but placed an order around the 19th September 2023 and trying to get feedback without any joy. The only way to commuicate with them is via Whatsapp which is an absolute joke. They just cannot help. I keep getting notified on the whatsapp chat that admin will contact me, but nothing. I am extremely dissapointed with my recent experience. Please can someone assist.
