I was at pejabat pos besar kl this morning. The officer was so reluctant to help me open an ASW2020 a/c, I end up renewing my passbook for ASM only.
Sigh, thought that visiting bigger post office would have higher chance / more friendly staff. I was so shocked n disappointed that the staff instructed me go to Maybank and try my luck without wanting to try for me at POS!

Yes. Upon changing, no. ahli will change as well. My ASM & ASW2020 now bears the same no. ahli, but not for AS1M at the moment as there is still no need to change the passbook for AS1M
