I'd return every piece (on their dime)of that and demand a refund. Covid19 or whatever else.....that's absolutely inexcusable.
If they knew you already had concerns/issues, they should bend over backwards to make sure you had ZERO further issues or delays.
They have failed you miserably twice now. If they refused your refund, I'd be VERY loud on all social media/knifemaking platforms.
Absolutely pathetic on their part. I wasn't considering buying any KMG (because of too many issues good friends have had) but if I was, this would make sure I NEVER sent KMG a dime for anything.
