Failed to deliver order and process refund

I am writing this complaint as a very dissatisfied customer at the level of service received from Connected Device. I ordered and paid for a new phone on the 29th Jan 2024 and i was told my order will be delivered within 7 -10 working days but that never happened , even after the company confirmed availability of stock and on the 13 Feb 2023 i was told that my order is not available anymore and they are not sure when will it be available and that when i requested for cancellation and refund and i was told 7 -10 working days for them to process refund and to this day 23/02/2024 i still have not received my refund. i will never order from this unpopular companies ever again. they even said they will charge me an admin fee for their own incompetence because i am cancelling even though i am cancelling due to their failure to deliver the my order.
