According to my friend who works there, VM or strictly speaking Virgin Mobile are shutting the place down with the loss of all jobs (about a 1000) as it is not just the call centre side but also the technology side.
It appears that they are outsourcing the jobs to - yes you guessed it - India.
Another typical attempt by a UK company to think they can save money by moving the role to overseas.
