Did anyone cancel their SkyFiber plan recently? How did you manage to do it?

I'm in NCR. We are moving to a new city in a few months, pero iniisip ko kung pano ako magpapacancel ng Sky. Kasi sa website nila there are only 3 channels to contact them: website "live" chat, messenger and viber. And i'm pretty sure na parepareho lang yung staff dito kasi isang araw halos inaabot bago sumagot.

How did you guys cancel it? Actually wala kaming internet connection for more than a week na, pero hindi naman ako makapag change ng ISP kasi nga lilipat na kami soon.
