They told me this too. So I went onto Compare the Market's livechat to ask them and they stated that it is not up to them to issue vouchers and the only offers they have to purchase through them are the meerkat offers (obviously). It's also obvious that they are lying because how would so many different comparison sites and MSE be responsible for issuing THEIR sign up offer. They have made me so angry!
Try and get them to pass this onto their "backroom team" Its a scam and needs to be reported to the regulator. I got mine, but I did have to threaten them with legal action. My daughter has still not got her's.
Trully awful service. Use facebook etc to shame the company
I got mine, I phoned them and was told you have to wait 90 days, which I was only a few days away.
It arrived as they said, by email, but it did go into my junk folder.
