I recently emailed NTC abt my problems with converge amd hinde sila nakialam huhu tapos converge send me an email na if gusto naming ipaterminate account namin kailangan naming bayaran yung bill namin na 6k to proceed with our termination. IDK WHAT TO DO NA 🥹 try ko pa bang ilaban ule yung with NTC and send them an email again or should i just ditch it? nskxksj
