Want to turbo faster, then need to do some legwork. Go to a tmpoint and tell them you want your turbo upgrade now. They will give you a form to fill in. It will take a few days or a week before they call you to arrange an appointment for the technician to come and check your hardware. Arrange our if you're sure your hardware is fully capable then tell them to just do it remotely.

it is called the customer retention form, only applicable if you are out of contract I think

From my experience, I went into TM Point to request for my turbo to be expedite, and my Unifi is still under contract. I told them directly I want to fill in the retention form to speed up my turbo upgrade process. Instead of giving me the form to fill in, the staff there say will help me to send a email directly to the turbo upgrade department to "expedite" my upgrade.

P/S : Just for a quick tips, 1st time I went there, I took the number and waited for almost 1hr. 2nd time I went again, this time I just queue at the Information Service counter, want make my request. If possible, take a look of the email that they send just to make sure they really did what they promise you. I went back for the 3rd time because I suspect they didn't send the email as they promise, and no surprise when I speak to the same CS again, it seems like they did send the email, but the Unifi account was not MINE!!!

I waited approx 2 weeks time as promised by the CS there, and my unifi was turbo-ed~

I am the one who managed to go to TM Point to expedite my turbo upgrade. They asked me to fill in complain form (yellow color) and at the counter the officer sent an email to turbo team to expedite my acc to be upgraded soonest. On my case they get my thumb print as proof my consent of expediting turbo upgrade.

Then around a week after that I've received my Turbo 500Mbps. Btw, I just subscribed to Unifi on July 2018 this year and of course still under contract
