What is your location

if the phone doesn't respond to any button and not even a charger,that's now a hard bricked phone.

You now need to install its ROM a fresh using your Pc because theres nothing else you can do to bring it back without flashing in a new ROM.

am not in nigeria but its something you can do yourself provided you follow tutorials on how to unbrick tecno phones.
But if you find someone who understands flashing ROMs,that would be easier and better.
