I did my unifi fibre termination at Menara TM back in Dec 2022. At that point, I was no longer tied to a contract. I was with unifi for 2 years+.

The customer rep did my termination on the spot. She also told me no need to return any equipment (I brought the BTU along that day). Then she asked for my bank account with a screenshot proof of my name and bank account number in a bank statement, for refund of any unused days. Got some refund a few weeks later.
