This practise is nothing new, you only have to look in the telephone book or yellow pages for 'local' instant call out tradesmen, usually advertising with a freefone number.
A few years ago (before we had house insurance emergency assistance cover) we had a leaking hot water tank. Seeing the problem and thinking that an expert might be the best and quickest solution, we selected and rang one of the companies advertised, offering local branch assistance. 'Local expert and tradesman' arrived having travelled 40 miles from his home address (on agency work!), looked at job and decided what parts he needed, vanished for more than an hour after visiting a local plumbing merchants 'just up the road' for a couple of regular plumbing parts, because he didn't carry any parts at all in his car. 'He' did the job, with me acting as an assistant and labourer, and I was presented with a final bill for £340 + VAT. A job which I have since found out would have been done truly by a 'real' local plumber who would have charged no more than about £130 total.
It still pains me to think of that 'emergency' repair.
Regarding Corgi, I had a problem with a central heating and a Corgi member. Corgi was totally useless in providing help,advice or assistance.
