Referred someone, no one called her on the day and she than went onto the website to sign up. She told the consultant she has been Referred to by me and they signed her up for car insurance. Now Miway say I cant get the referral voucher because she went tlon the website and app****. Yes but she told the consultant its a referral but Miway say now there's nothing they can do the referral voucher is not applicable because she went online. I will never refer someone again!
