A couple weeks ago, I moved from Sky to Virgin. Due to a fault in my line, and the fact that a construction team couldn't be sent out until the 21/8, I had no option other to move back to my Sky provider, as I simply couldn't wait that duration of time without my landline phone and internet.
Upon sorting out my new contract, I was recently provided a new landline number by Sky. However, I have recently rang Virgin and they told me that my old landline number is still active and will be until the disconnection date on the 27/7/20.
Is there any way of retrieving my old number? This is a number my parents have had over 30+ years.
