Please update my latest bill. TQ
Just to let u know, this is not an automated request board on an app. It's just a forum where human input is needed. It won't have the intelligence to detect your mobile number or account and update ur bill =(.
What you can do is to reach out to Celcom as per below;
"As this is an account specific issue, please contact our direct support agent as we will need to have your personal account related information. You may click on this link https://www.messenger.com/t/celcom for assistance. Alternatively you may also call 1111 and speak to one of our Customer Service Consultants."
Hope this will help!
