Sama clearance

I have paid all dues of my credit card in November2017, but i came to understand that still my name is under SAMA as a block list, how can i get clearance from SAMA? and how can i check myself through online?
please help me sort-out this issues

Hello sir, have you cleared your name in SAMAH Blacklist?
If yes, then how did you do it?
Also, is it possible to go on a Re-Entry if anyone is blacklisted even after paying all the dues??
