Tokyo gas # for cancelling service?

*sorry for the almost identical post to earlier, I made a mistake in asking for the TEPCO number instead of the Tokyo gas one. Thank you!!!!*

Hello!

I am currently a resident of the West-Tokyo region (Kanagawa pref) due to a sudden illness in the family I have to move back to Australia.

I’m aware I need to cancel all my current utilities but, I’m having some trouble finding the Tokyo gas number that allows you to cancel service. Does anyone know of it? I can only find customer helplines when googling in Japanese or English.

Thank you very much!
