I recently ordered an A+ course update from Macmin Technical Training (click here) but my order was not complete - it was missing an A+ 2003 CD which I was promised.
I have recently found that they seem to have ceased trading - their website has been taken down. Emails and letters go unanswered. I am unsure about what to do about the missing CD I was promised. And I doubt I am covered by any payment protection as I paid by cheque.
The trading name is not the actual registered company name in companies house records. There is a 'dissolved' company registered, which is similar to Macmin, but as I say,is it similar and possibly nor Macmin as you suggest.
If the company as folded or gone bust, then any funds [if any] will be in the hands of any administrator or receiver.
Looks like you will have to count your losses, and put it down to experience, as it would appear as though Macmin, as you know it, are no longer.
