went to the bank yesterday. surprisingly, they do not even know they got visa signature . i asked them to check their web, then they tell me will ask their manager about it and call back to me 

replying ur statement above.
I did paid thru CDM previously, many² times and end up the HLB CS calls me asking me when i want to pay my hse loan since their system shown i havent paid yet. Every 2 weeks the CS would call me asking me when to pay when i had already paid. This happen for 3 / 4 months then i got fedup to pay thru CDM & paid at counter. The best part, the issue still occurs but not sever as the CDM issue so i prefer to use counter pay rather than the CDM even if i have to queue up for so long....

he already complain to BNM and was told to wait

no, do not screw HLB, their legal department will then handle the case and it may back fire. Write an appeal letter to Tan Sri personally asking for his "help" telling him his people are bullies and he paid good money for a bad system that does not work properly.....
