The points you may use to redeem for you bill rebate for the account that is still active. Should be no issue for you to redeem if you have sufficient points to redeem for the bill rebate. Regarding on this issue, it is best to refer with their support at 100, Live Chat or PM them at @weareunifi (FB) or DM @helpmeunifi (Twitter) or directly click this link https://unifi.com.my/support/contact-us. Hopefully there is someone in this comunity can share their experience also with you because as far as now I did not have issue to redeem the points for my bill.
Thanks for sharing. Unfortunately, those suggestion that you mentioned i have tried more than 10times and chat with the agents more than 2months.....anyway, thanks. I will continue to looking for help or else will only cease to use unifi & TM since i'm not VIP user for them.
