Misleading information regarding Fibre line release.

I have cancelled my Fibre package on the 7th of May , the cut off was the 30th of June. Today is the 5th of July and I cannot move on to a new service provider, as they are not releasing my line. Worst part is that they, claim to have released the line when you phone them, they give you reference number like your ONT Serial number, but they don't do anything about it. I work remotely and have been struggling the whole week, VOX please be honest with your customers and provide valuable feedback, There is also no way of calling the people who deal directly with these line releases. So yes have been a customer since 2018, but I'm so glad I'm moving away from this company, they have no after sales service.
