In your original post you say
"The old number had been in existance for years and so is on my business cards, friends contacts etc etc etc and in one swoop you have lost it."
Then you say the telephone line was disconnected by previous owners ????? Yo say in a comment above that you only had the number a week before reconnecting with NOW hmmmm strange ..sounds like you need to get your story straight. Probably why NoW aren't bothering lol
Just had the same thing happen to me. I specifically said that I needed to keep my old number when switching from Virgin. No notification, found out when people said they could not get through to me. Checked my outgoing number and found it had been changed. Spoke to the support team on the phone to be told it was too late and the number has been lost! What can I do in this situation?
I seem to have a similar experience with Now TV - what a load of ###### they are. First my old provider continued to charge me as well as Now TV- you try contacting them during covid19 complete waste of time and cost me money. Today I find out people have been trying to contact me and cannot... guess what, after a lot of messing around I have a new number and my old one is 'invalid.' I think this is recent but I have a sneaking suspicion it has been this way since the changeover on the 19th March!! Nice of them to let me know.
Same thing happened to an eldery relative that I was swapping over - Now TV take no responsibility and the old provider can't do anything.
They advised that we could cancel the line and retry the order, so we cancelled and redid it and it failed so now have no telephone line, no number and an eldery relative that is vunerable. Avoid Now TV like the plague...!
