Was impressed b One Call and the ease with which they could set up car insurance for you. However, when I came to add a further driver for a week (daughter visiting) their response was the underwriter would not do this and the only way to add the driver would be to cancel the policy (for which there would be an admin charge) and take out a new one with the driver added. Alternatively I could add the driver for the duration of the rest of the policy for and extra £220! At the beginning of the call I asked whether they would insure a person for a week and the answer was yes. Wasted 40 minutes of my time. Will look to go elsewhere on renewal. Not good customer service.
