OneDayOnly Order #***

On 5 June 2020, I ordered an item from OneDayOnly, which at this stage hasn't been processed, despite their promise of a 5 to 10 day turnaround time. Despite 5 emails to their customer service, I am still getting automated responses that have nothing to do with the issue. At what point does an organisation get so arrogant that it refuses to accept calls, and simply keep money without delivery?
