Ball is rolling!
I asked my brother to ring from his phone over the weekend, he had problems getting through he said so I left it until today and rung the 0800 052 2000 from a friends house today and luckily managed to get through in 5 minutes!
Explained the situation, was told to ring another 0800 number and ask to be reconnected. Spoke to a nice Scottish lassy named Debbie and explained again the problem, she spoke to disconnections and verified both had been disconnected so she filled out a 'reconnection form' and told me to wait 3-5 days for it to be reconnected and that a letter will be sent to confirm the reconnection.
I also asked about compensation for the inconvenience, it wasn't my fault after all, and she said I would be compensated but not the details, so can't grumble really!
So I'll find out in the coming days whether the phone gets reconnected!
Just don't call me, cos I can't call you
