thanks all, I send my Co an email letting her know about the name changes.
As they already done the employment verification and told me they were waiting for my Medicals to be back from Medical assessor to do the final assessment, I didn't give the new boss number as on my application was my boss emailthat didn't changed (and shop phone number) , I'm sure if she needs anything she will ask for.
Therefore, I emailed her new information yesterday and also requested any possible update because she told me a couple of weeks and it's been a month now. But she didn't answer my email yet....
