Number transfer process

[#1]

I took plusnet mobile deal couple of days ago and received email that my old number will be transferred from virgin to plusnet on 9.2.2022 but nothing happened.
Called customer service yesterday after 5pm and was told that the line will be transferred after midnight, but its 11am on 10.2.2022 and still nothing happened.
Need to know why, hope I didn't do a mistake by leaving my old company

I do know Virgin have been dragging their heals on number transfers both in and out
