Unacceptable and shameful service

Placed an order on the 24th May and my order has never arrived since then. No contact from Checkers. The order was pending on the 24th and 25th. On the 26th the app was updated to cancelled. No communication from Checkers even after I called them numerous times and I have logged a complaint via the Call Centre and I logged 2 tickets via the app Help Centre. When calling the Contact Centre the consultants responded in a scripted fashion by apologizing - however completely lacked empathy for the situation and had an attitude telling me that I just need to be patient and that my good will be delivered. 3 days later no goods, no refund and no communication from Checkers Sixty60. Other consultants I spoke to promised to call me back after I requested feedback. They have all consistently failed to do so even though I have mentioned my experiences of empty promises from previous consultants. How does Checkers justify taking money from people's bank accounts without delivering goods and services? I understand that mistakes do happen, however the true test is how they have dealt with it. I see that I am not the only customer who've experienced a similar situation. Unacceptable and shameful service. No follow up or accountability. Also when do I get my money back in my bank account?
