DTAC Customer service : how to reach them from abroad

[hetepatat]

I tried cancelling internet on an other card and it dissapeared from my services list immediately in the e-services.

I needed the DTAC Customer service to cancel my unlimited internet while i keep the phone abroad, otherwise it would just keep on charging me the 399 baht per month.
So i was searching for the number to call when i'm home so i can cancel the package as no other way of cancelling it will work from outside Thailand.
I don't want to cancel it from Thailand in case i would not be able to use the service any more before boarding the airplane. I want to make use of it until the last second :-)   


I found the following information and checked it on an IP phone service and it works..
