Well, well, did I ever have a surprise this morning.
I had received the Revols package after my Kickstarter optimistic support, but my left ear was too small for the medium and large earbuds they supplied. I ordered, and paid for, extra-small earbud in May, five months ago.
I didn't hear a word from them until I wrote them in August. I was promised (via a support ticket) a fast sending. never happened. I had written twice in the last two weeks, and got no response.
A couple of days ago, after I read the comments on this website, I wrote to them with the history of their non-responsiveness and said it was beginning to sound like a company going bankrupt and scamming current customers to pay off past debt. I asked them to prove me wrong by responding and sending me a trackable package.
I was not optimistic.
I came home this morning to find a UPS package with my XS earbuds! Amazing.
