Most unprofessional company I’ve dealt with

Ordered an iPad on 25 November 2022. Didn’t receive it yet. They tried debiting my account again on 25 December. Received an email from Tazlynn Adolph threatening me with a charge of theft if I do not return the item (which wasn’t delivered). Then received a call from Caleb on 26 December asking me when I’m going to pay for the item. When I told him that I hadn’t received it, he asked me if I was sure. I cannot call the company. I have sent several emails with no solid response. I’ve tried their chatbot which is useless. It’s very difficult dealing with such poor service.
