Tiscali have now admitted to their email service not working. Not only that, but other email addresses have not been working through Tiscali as an ISP (if used through Outlook.) That is why I have not been able to communicate with anyone on either of my email addresses.
I am furious with Tiscali, who failed to warn their customers of the problem. I had been sending emails into oblivion for a week before I twigged. I missed appointments and lost work in consequence. What is more, the emails will not have been stored by Tiscali and resent once the system was up, and I had not saved all, as I regularly clean out my sent items.
The system is now allegedly working. Anyone awaiting a response from me on anything, please email me again.
