I am most grateful for the supportive messages, thank you all. In response to the matter of what I expected for my money, no I did not expect to be given a "free" paramotor and wing with training included for next to nothing. Simple arithmetic soon excludes that possibility.
I only expected what I was promised: the [loan] of the equipment needed to achive the result I had paid for, for the period of training, with the expectation of paying for anything I busted on the way. The charge made seemed concomitant with this.
Activity of this type seems to have such currency that the legal eagles have given it a name: "Bait & Snatch". (An attractive item or service [bait] is advertised, but is yanked [snatch] smartly out of the way after payment has been cleared, to be replaced with something inferior or nothing at all for the customer to receive.)
How to avoid this trap? No guaranteed method, but personal recommendation obviously has value, and getting it all in writing at least precludes any differences of opinion. I still believe that there is no reason to pay for more than a day in advance, which at least would limit losses.
As has rightly been suggested, no PMC people were involved, all I know of Simon W et al indicates them to be of the HIGHEST calibre in honesty and morality as well as ability. I have also had dealings to some extent with Paul Williams at Paraventure in Wales, and Chris Dawes at Airways Airsports, also Clive Bunce and believe them to be similarly trustworthy.
I appreciate the concerns on the self training front, I will consider my options as they arise. I have bought a wing and harness with which I am becoming quite proficient at kiting - when I have that cracked I might seek help to proceed, but I currently feel I would prefer to only have myself to blame for the results.
Now, I can only afford a motor OR training, not both.
I do not want to start a witch hunt, another reason for not naming and shaming the people involved. I hope that frauds like this are ultimately self limiting as word gets around: the perpetrators have to either change their ways voluntarily, get forced to do so by their customers or are shunned. But word MUST first get around, a great value of this forum.
My only wish is to help others from falling down the same embarassing hole that I did. If I achieve that I would be happy.
