M1’s customer service is terrible. Called the hotline a couple of times but the staff could not resolve my issue. Did an early termination of my lines subsequently and the M1 app immediately removed my numbers so I cannot view the final bill. Not sure how does M1 expect their customers to pay their final bills when the bills cannot be viewed? Got onto M1’s FB page to post my feedback. 3 days of wait and they are still trying to find out what my issue is. And that is after I provided them with my lines, the last 4 digits of my NRIC and my DOB. Thankful that I made the decision to terminate my contract with them.
