Yes, it would make sense that they want to put some kind of lien on your account to cover the second device. That would be fine even useful for many, if, and only if, they also allowed you to return a faulty device without receiving a replacement, apparently they have confirmed this is not possible. Their last email was effectively 'Our way or deal with the manufacturer'
My issue is I don't and can't really afford to risk another £200, even if the risk is small that they won't deem it under warranty. There is also the risk that the item won't make it to them/they lose it.
Surely such a policy can't be in keeping with consumer legislation? it is putting an unreasonable barrier in front of one exercising their statutory rights.
