In January, I went to Maxis Centre to terminate my WBB. I asked them to terminate in two days' time but the CSO said cannot, must terminate immediately. She suggested when I'm ready to cut in 2 days, just call 123 to end the service. So that's what I did; on the day I wanted to cut I just called 123 and they asked me some personal details to verify that I'm the genuine account holder and then it was done. Within an hour of that call, the my WBB was terminated.
