DriveU sends offercode after it expirs. How foolish.
They send me offer code notification on 17dec 2017. but it didnt work. and I asked them why it is not working. Also, I have to give them proof that they sent notification of offer. I have been told that offer expires on 30 November 2017.
And it happens many times. I simply feel that they dont have any offer. just they are trying to attract customers by sending vague notification.
