iStore online don’t care

Purchased an I-pad mini on the 11 November 2024 via the online iStore. Purchase *** No acknowledgment of my order. They say their internal systems may be a problem. There was no stock at the time so delivery was estimated at 2 weeks. I have a string of e-mails. Still no confirmation of my order or estimated delivery date. All communication from them is meaningless and lacks substance. They do not answer my questions. They say they have escalated my issue to top management at head office as well as their supply chain management. They cannot tell me who these people are and I still have not received a response. I have asked for the name and contact details of the CEO. My requests for this information has been ignored on 4 occasions. Where do I go from here… Please help Kind regards
