Sales Lady basically told me its my problem for no connection between my move to a new premise

I have contacted VOX on the 17th of December to cancel my current fiber line as I am moving , I asked the sales person can I cancel my fiber and then re-apply for the new premise , I have been a vox customer for a year now , the lady then told me i have to cancel it then can only apply for the new line the end of January and the new application can take 2 to 6 weeks , when i told her i can't as I work from home se said thats how VOX work and i must look for another solution till the fiber at the new place can be installed , her attitude smells , I will never use VOX again , my family and friends who have business account will also move .
