When it is 39 hours 36 minutes.
More importantly when it is our favourite telco measuring how long they have had a fault report and working to a 40 hour target or else pay use £1.50 compensation!!
It has happened far too often now to be a coincidence. Faults clearly with them for many days have the clock magically stop at 39 hours something.
Raising the issue has simply got no response from them.
Its got to be a con I my opinion.
