I am amazed this thread is still going! Moonfleet has responded and their account is very different from that of the (now silent) OP.
And yet posters are stilling raising issues that are either nothing to do with the post - such as what makes or does not make a good course, are RYA certificates worth anything, or is a full English breakfast a good thing, or should the website be different , what makes a good service business, whether Moonfleets courses are "bistro" or "fish and chips" etc etc. These are are all good subjects for discussion, but not in relation to an alleged dispute where none of us knows either party, were not there, have no other involvement and therefore are not in any position to make a meaningful comment!
