If you pay in advance for a year and decide not to have certain features how would you get a refund, would you get a refund and would others (not you) complain if they did not get a speedy refund or any refund.
I do not normally pay my water, electricity, cable, cell phone, land phone, internet service, cable service, mortgage or other monthly bills in advance.
