eta on MMM's ?

[Wild YFZ 450]

I sent my MMM on the 1st using priority mall ( 2-3day ). I Just got an E-mail on the 14th that they received it. This is after I sent numerous e-mails asking about the repair status, which I never got an answer for. This was because I hear they where out of MMM's for a few weeks. I never got any response from any of my e-mails. Castle is a great company and great products but I never get a response from there customer service.

Basically what im trying to find out is when the MMM's should be back in stock?
