When Will I Be Eligible To Earn Hextech Crates Again?

So I got banned from league for 14 days (Which happened about 2 months ago) and yes I can still be toxic at sometimes still but I feel like I have been better. but people still don't honor even I when I think people deserve it I forget to honor them so I am here making this post wondering if there is a straight up way or time limit to where I can be eligible to receive Hextech Crate and keys again.
