VOX CONSULTANT HOLDING LINE AT RANDSOM - no reason for not releasing the line

I moved house and is now dealing with 3 wifi suppliers all fighting for territory. It has been 2 weeks since we moved in and the worse one that is holding us up is VOX. Worse service ever. I was told last week they are releasing the line in 48hours. Then to phone again last week friday - then Philip Kemp the consultant told me that the previous tenants still owe money on the account. Although previously he mailed everyone saying the account is cancelled and all perfect. Then he told me to phone accounts. Then I phoned accounts and she said - there is no outstanding money. So contact him again today. No answers just vague answers like we will let you know... According to him the line was suppose to be released last week. I am not sure what is the hold up. Literally costing me a lot of money buying pay as you go as I work from home and need to run meetings on Zoom. Just so frustrating that they cannot give me a solid answer. THEY ARE THE WORSE SERVICE PROVIDERS AS FAR VOX.
