BNM should probably come up with a guideline like this and enforce it.
1. If user has credit cards from 2 issuers or less, then come expiry... nothing happens.
2. If user has credit cards from 3 or more issuers, then when the first card expires it will automatically be terminated by the issuer. This will go on automatically until 2 issuers are left. This should force the users to choose which ones to keep, and which ones to terminate.

I will have to return all my cards to the banks should the new ruling be fully enforced. Coz I don't fulfill all those income requirements
