I know of at least two people who never had their ordered goods delivered, so this statement is untrue.
To TBI's credit, both people did receive full refunds, but just pointing out that there have been at least two instances where they were unable to deliver goods ordered.
And this does not include my MP Cordon which was never delivered, as that was the courier's fault, not TBI's (and TBI did refund me). In the cases I'm talking about the goods were simply never delivered at all.
