1. Mel's question
led to the answer that ebuyer is generally reliable and has paid commision in good faith elsewhere.Is this the only transaction that e-buyer have refused
2. Richard's info
I think that the general position should be that imutual shouldn't pay out in these cases.the claimant is a long-term member of the site with an excellent record of contributions
However due to point 2, in this case maybe a discretionary goodwill payment could be made so as not to open the gates to bankruptcy ( I know that i have been on the benefitted from imutual's goodwill & trust in the past).
As an additional point, I always close all browsers and use ccleaner to clean all cookies before purchases. For insurance purposes, I use slightly different criteria on the price comparison sites to the criteria that I will actually use to buy the insurance, so that they do not have a matching quote.
