Well...this is a lot to take in!
While dreamkastor is correct, we can't help you since this forum is owned and operated by the U.S. distributor, The best thing you can do is figure out what is going on at Efkay.
Efkay is how your issue will be fixed...unfortunately I don't have any more info on them than the general contact information located on the Tama site dedicated to Canada.
we are completely seperate entities...
Have you spoken with anyone there directly? or just your dealer? did Efkay tell you they were replacing it?
sending in pictures of an issue always helps and having an accurate timeline of "when you spoke to who about what" will also help your case.
The only setback I see that could hurt you is time...have you sent them back the incorrect drums? I'm just wondering if maybe some lines got crossed and Efkay may have a different understanding of the situation.
I would call them for sure.
