Termination of account simply means the company has / is going to cease the financial agreement that you signed for and will / may require you to repay any existing credit / outstanding payments within X number of days. However you also mentioned that this is not your fault - because the company did not process the deferment request in time - Write to the company explaining the situation - provide them with copies of all letters sent and make sure you mention that you are engaging the first level of internal complaints proceedures with the company - Normally after the second level (if you are dissatisfied with your level one resolution) you may have to escalate to level 3 / head office. If they give you no joy either - THEN and only then must you contact the ombudsman service if they are regulated by the FSA - which if I am not mistaken they are.
