For EU buddies: there are tools designed for disputes between consumers and traders in the EU, Iceland, Liechtenstein and Norway. I had to use it once with BestService and was entirely online, free and fast (within a week,IIRC).
IKM is Italy-based, so, those within the EU affected by a legit MODO DRUM 1.5 SE unqualifying product for the GB *maybe* could get european customer policies protection. It might be worth a try go for a Online Dispute Resolution for unfair-treatment/commercial-practices.
