What is it that you're "disgruntled" about? I don't get it. The fact that they even remotely entertained you shows good faith and professionalism on their part. Your request is utterly ridiculous.

The issue wasn't them being stingy on the 30 day policy, the issue was someone who bought parts 3 years ago (or 2 or 1, it doesn't matter -- it's being measured in years, not months let alone days) never inspected them and then put them in storage for all that time. They were actually quite accommodating given that they even entertained the idea of replacing the parts. Since they spent an hour on it then called the OP back, I'll bet they actually made the effort to see if they could replace the parts and found that they couldn't for one of any number of possible reasons. Not the least of which is that they may not even get the parts from the same place any longer.

Actually this thread is the perfect example of why vendors should be kept anonymous in these discussions. Because now you made a thread "calling out" Marco when they did absolutely nothing wrong whatsoever. In more modern lingo, this thread is "FAKE NEWS".

What does "should" even mean in this case? The letter of the policy is super straight forward, but being that they are a great company to deal with they even entertained the OP and looked into whether they could replace them. This is despite not having any clue whether, 3 years later, these are even actually the parts they sold. They could be used or they could be from somewhere else. Or they could be from them but they have since switched suppliers and have no recourse of their own.

But 3 years down the line, they shouldn't be expected to give an explanation for anything. It's absurd to think they should. They looked into it, they found they couldn't do anything... Whether that's because they didn't want to or because of some other reason doesn't matter and isn't a reflection of their customer support.

Someone mentioned car parts -- that's different. If you are a shop that has an agreement with a supplier about parts that's a whole other animal than buying stuff at the consumer level. Maybe the OP should consider that if they are holding onto parts for so long. Make an agreement with Marco that they will buy $X per month (likely measured in the thousands) in exchange for this type of relationship.

I got ya, I don't know why I even bothered to talk about it. I have no idea what you're talking about, you're not even mentioning what types of parts you are referring to. I seriously doubt a car parts seller is going to send a replacement glove box hinge after 3 years... But if they do then awesome: tell them to start selling pinball parts too.
