Warranty replacement RB21T remote required

Telus Digital TV remote - RB21T, in need of a warranty replacement (had service/remote since Jan 2026). Remote no longer holds charge of batteries, have changed multiple times from different brands. Have also researched and tried resetting, unpairing but not possible due to remote losing charge within seconds.

Green light is solid and white light flashes after inputting batteries for approx 13 seconds, no commands are possible from button presses on remote before all light dissappear and remote is dead.

TELUS support services, please help!

Thanks
