I don't think you understand what people are "complaining" about. I understand the TAT are estimated, but when that so called estimated TAT doubles and triples with no warning, people are gonna get pissed.
I had a standard sub with a estimated TAT of 45 days when it arrived at CGC a few months ago. When I got my cards back it was roughly 130 days.
The estimated TAT has gotta better over the last 4-6 weeks with everything leveling out with people sending in cards etc. But the TAT times posted before are a complete joke and hardly a estimate. Just a crazy wild guess. I'm getting my childhood cards graded with my sons modern cards as a hobby for us to have something to do. Every person complaining is not a Ebay seller.
A company can do a million things right but the majority of the time people only talk about the bad as you see in these forums.
Don't even get me started about the crappy cardboard insert they use when they ship your slabs back to you that damages them during shipping... but over all, I have had mostly good experiences with CGC so far... Hope all is well old timer and may each day be easy for you. 🙏
