I don't like celcom's web site... http://www.celcom.com.my
If I have to rate it, I'll give 1 out of 5!
I got lost for the first few times I visit the site just to help someone to manage his CMT. If not the case, I won't visit the site. I was in hurry and still have to use my time to dig out where is the place to log in for the CMT. At the time I reach the CMT login site, I've got the message "HTTP 500 - Internal Server error".

celcom SHOULD DO SOMETHING ABOUT IT!!!!
(I'm still disappointed having such experience visiting that website)
