Maxis Service is very bad, i opted to switch to a different Telco and my request to Port Out has been consistently rejected with the reason "did not respond to SMS to port out", i had responded many times and within the timeframe give, i have even called the customer service to ensure that it shows in their system that i have confirmed to Port Out, yet it still gets rejected. I had requested for a call back from Port Out division as the customer service agent at 123 was not able to give further details on the "technical error"...it been 2 weeks and the issue is still not resolved. Their Customer Service is really terrible, its best that you do not sign up for any maxis plan and use the other TelCos in Malaysia.
