It is virtually impossible to speak to a customer adviser. The IVR system is not fit for purpose. They send you letters to tell you to call them for a refund if you are in credit (their mistake). You cannot get through, have to listen to a woman repeating herself every few seconds and some ping pong music in between, often for up to an hour or more. You are advised of an option to call back or go on the website. The website doesn’t answer questions and you cannot send a message. Do not get an account with this company.
