Brad,
Thanks for letting the community know about your sort of 'uncommon' experience. Having a package sent to you, with all of your information correct, the only issue being, that 'it's not your item, to begin with,' would give me serious concerns regarding our internal tracking process for 'repair items,' if I were IM's owner. Although perhaps this is the 'one in a million' failure of IM's tracking system, maybe it isn't, because some people might not be as honest as you are.
If I sent a locomotive in for repairs, and never received either an acknowledgement of receipt by the manufacturer, or return of the product I paid for, that didn't work properly, within a reasonable amount of time, I'd be fairly angered and frustrated by the experience.
Given the whole way the hobby has gone in the last couple of years, regarding factory installed decoders, details, + newer drivetrains, etc, and the lack of the typical purchaser to 'fix it themselves,' and/or reliance on a 'factory located repair service,' it makes me sort of miss a less complicated time, all these bells and whistles were 'the only way to go.' It is very reassuring to know that at least one company realizes that 'mistakes can and do happen,' and that not very customer is dishonest.
I agree with everyone else; it reassures that there is still at least one honest man, and one company that cares about its customers, left in our hobby. Thanks for making my day.
