Link Mobile account to Broadband account

[#1]

I understand there may be an increase in data allowance if the user also has plusnet broadband - I've had a plusnet broadband account for many years and mobile for the last couple - I've just never got round to linking the two together.  Is there an easy way to solve this.

Hi there, I can sort that out for you. Can you send over a PM with your broadband username and your mobile number please? - Adam
