The only situation I could think of where I would do that is if I received a faulty pedal and the resulting customer service was poor.
I get that mistakes can be made in production, but if you're not doing your best to resolve the issue for the customer then I'm sorry, we're done.
I'm currently going through a situation like that. Fortunately they are responding, it's taken a few days but with the current situation and with the manufacturers being only or two people, I feel the delays are acceptable. I'm also willing to problem solve myself with their help. Id rather the pedal was fixed and working than have to send it back to the US (im in the UK), them to fix it and return it for me to pay a second round of customs fees.
I will say that I have written off a brand on the perceived attitude they had on social media. I bought one of their pedals and did a demo. They commented and said "hey you should buy our (pedal) it's great on bass"... I replied and asked if they had any demos as I can't find any online and its not cheap or easy to get that stuff in the UK. No response. I just found it a bit rude. Like, you want to interact with a customer and all you want to ask them is to buy your new thing but don't want to put any effort into actually sell it? I'm an easy sell, it's not hard to sell me pedals!!! That simple interaction soured me on them. I'll spend my money elsewhere.
