R40 interest section

Unfortunately because you chose to use a third party it's difficult to know where the fault lies but as you have evidence of the tax all you can do is phone HMRC and explain the calculation needs two revisions, the gross interest should be £4343.  From which £868.65 tax was deducted.

If it a Simple Assessment you have received then you have the right to formally appeal it and can provide the proof you have.
