Hi there, I paid the bill from the cancelled DD that was passed to their agency. I specifically recall calling VF to cancel the account. They are saying they have no note of this cancellation, yet the debt has no increased. Surely if the account was not cancelled the debt would have increased?

here's my situation. I appiedy for a mortgage and it gets declined. Head over to credit file and see a default going back to 2015 from Vodafone for £30. I had a sim for an Ipad for my job at the time. Left job, cancelled DD (stupid I know) then 2 months later get emails from debt recovery, pay instantly then call Vodafone to cancel the contract. All fine and dandy (or so I thought) I received no emails or emails chasing the money so assumed all ok. I call VF today to explain that this account was cancelled and I don't feel I owe the money and for them to remove the mark. "ok sir we will look into it for you and call you back" A few hours later I receive a call to say that there is no record of the cancellation and I owe the money, but if I pay the money they will review the default mark. I pay the money, am placed on hold ready to be transferred to the credit department. The handler comes back and advises that they won't remove the default. I explain that this is crazy, they are ruining me and my family for 6 years over £30. And that had I had known this was owed I would have paid it instantly (as I did today) he puts me back on hold for a while. Again the answer is "no" Do I have a case here or do I need to suck it up and live in financial purgatory for the next 6 years? Thanks in advance.
