Phoned Aviva, formally Norwich Union, for a maturity value and was given a figure well in excess of what was owed on my mortgage. Out of the blue after the mortgage ended received a letter from lender stating I had underpaid in excess of £3000 on my mortgage. Phoned aviva and spoke to several people over the phone all of them agreed they had never seen a case in such a mess but despite assurances that they would phone me back to update me on the position they have failed to do so. The lender is now attempting to pursue interest on amount unpaid and have put penalties onto my account. Aviva have happily taken my money for 25 years and when it comes to paying up they mess up big style. Stay clear of this company
