Dishonesty at it’s best

In brief, placed an order for item advertised received a quote paid the requested deposit (50%) in October 2023 was quoted 10 - 15 working days delivery, followed up middle November and was sent pictures of components in manufacturing, followed up again in December was informed item was completed and will be ready for delivery by end of the week, when I messaged to arrange collection was informed that the business had closed for Christmas. In January business sent me paperwork to register item, on closer inspection paperwork appears incorrect and immediately queried only to be informed that I had been sent wrong paperwork and correct paperwork would follow, I then received no further communication with the manager ignoring all my messages. I then sent a demanding message to which I received paperwork albeit almost 6 weeks later. I asked for photographs of the item only for photos to show an item that was not what was advertised. I requested a full refund of my deposit which was agreed to. I received a little more than a third of the amount and was promised the balance within a certain period of time this has not happened. I managed to get hold of a person who claimed to be the owner and he promised to get the payment resolved. It appears that my numbers have been flagged and I am unable to contact this company. They do not respond to messages nor answer calls.
