I seem to remember a few years ago when London coins had some kind of Investment Portfolio thing (with a different name) selling slabbed PCGS coins. There was a membership fee which was refunded after a certain sum of coins was purchased. I'd amassed nearly that sum buying things for a client and then they stopped it and started CGS and slabbing them themselves. I asked about the membership fee, if the total credit could be passed on etc. Got a reply weeks later after a further email saying 'No'. Absolutely terrible customer service, always.
And now this happens, which looks very similar to me. Not a good show at all, and all the £99 and £499 subscriptions fees smack of desperation to me.
