Just sharing my experience downgrade my unifi from 500 mbps to 100 mbps earlier..

I received turboed somewhere in Sept 2018 from 50 to 500mbps but unfortunately I unable to enjoy the speed given due to my own devices (max 50 mbps for 2.4g wifi / max 150 for 5g wifi / 350 for wired connection). Already ask the technician for ground assistance which they told me the speed is based on what have been promised (500mbps on wired and 300++ on wifi)

Thus, since my own devices are not capable to get the speed more than 100mbps, i decided to downgrade to 100mbps and need to tie another 2 years contract. after few days they send notification to off my router and enjoy the new speed. Surprisingly, when use wifi i can get 75++ mbps through 2.4ghz + 100mbps 5ghz. better than 500mbps earlier.

and also during submited the downgrade form in tmpoint, i saw lot of unifi subcribers terminated their account..i feel sorry for tm but i asked the staff why so many terminated like pasar malam meh, the staff told me only here they can terminate the account..haha tm make things difficult for those want to terminate unifi acc.
