PSA was never created to please their clientele. They know they have you by the short hairs with a vice grip.
Customer service - leave a message
One year turn around times - or pay more for expedited grading
Larcenous pricing - worth more than the card without a slab
Deaf ears to complaints (like these threads) - don’t hold your breath
The bottom line is the only number they look at.
As long as their mailbox is filled daily with submissions, everything is fine.
They are a virtual monopoly, having been blessed by the hobby and the registry.
FedEx and UPS impacted the USPS decades ago. Who will impact PSA ???
PSA, with their market share, doesn’t even have to respond to their competition.
Have a great day.

PS: They have never got a dime from me.
