Or those who use O2 services, including those who lost money, those who lost business..!
I have a problem with those people, first, unless they have a business account they are using their accounts outside the terms and conditions which they have agreed to and thus should under no circumstances be reimbursed for any "lost business".
Rather they should be booted off the network for breaching the terms and conditions of their account, or at the very least, they should be forced to migrate to a business tariff and made to pay compensation to their network provider for breaching the terms and conditions of their account.
As for everyone else complaining about having no service and ending up in difficulty, I'm inclined to ask all of them, a) Why didn't you have a backup ready to go? and b) Why didn't you go pick up a SIM card for a non-O2 network if your need was that desperate?
Seriously, they could all have gone and picked up a 3-2-1 SIM from Three and been back online within minutes, if they'd have picked up an ASDA, (EE), SIM they come with free minutes, texts and data for network testing, and Vodafone have a £1/day tariff for the days you use it which is unlimited minutes, texts and 500MB of data. Both Three and Vodafone have a £5 minimum topup too, so it would have cost just £6 to have covered the whole outage and save people from all the angst and drama.
The whole episode and all the complaints demonstrated little more than the vast majority of people have given up any and all sense of personal responsibility and expect everyone else to get them out of messes their choices and behaviours find them in.
Human beings continue to disappoint me.
