What we sometimes see @Maries9 is that when the account holder ends the contract they then cancel the direct debit which then does not allow Vodafone to collect any remaining amount.
It can take Vodafone 2 to 4 weeks to produce the final bill.
I understand what your saying about being contacted to collect the outstanding monies, but if Vodafone feel they've exhausted all means of collecting they can engage a debt recovery agency.
They can then also without any requirement to let the account holder know apply a default that lasts 6 years.
Paying the amount is the first step which should change the default status from Outstanding to Settled, however the default remains in situ.
I would suggest that you now contact the Vodafone Social Media Team's via Contact-us-for-account-specific-queries as they have a Credit File Specialist Team who can investigate the default to consider whether it is warranted or not.
I know from my own personal experience how damaging a default can be so I wish you all the best with this.
