Expanding on (c), as I say I worked for Spark and Telstra Clear and (certainly at the latter) people would call up every month and expect to get their entire month's usage free, even though their internet was down for all of 20 minutes or some other very short internal. Some would even get into screaming matches on the phone as they felt it was "unfair" when told no - not realising the connection is "best effort" and not guaranteed...but they thought their $80 a month connection was a top-end, full premium-grade service with guaranteed SLA's and uptime, and blah blah blah...they would argue until they were blue in the face that they should get a credit.
If you think that sort of thing never happens, trust me, it does. Regularly.
I appreciate that, however I would ask (for the second time in this thread) what makes telcos different from other service providers. I suspect the same group of entitled people probably also ring up their power, water, etc companies and demand a big refund when they have e.g. a 20min power/water/etc cut. Yet these other non-telco service providers still make the effort to communicate about outages. I think it's just part and parcel of providing a service people rely on. Best to provide the information transparently so that people can benefit (and I suspect more people than you realise would appreciate this). Why have a few bag eggs ruin things for everyone else?
