£150 reward for switching

[#1]

We switched broadband this week. For doing this and choosing the package, it said we would get £150 reward voucher.
I have had no email or letter stating any information relating to this.
Any help on how to track down and claim it?
Thanks

I would like to know how it works too. It was advertised as a reward card for my sign up.

@Gemmarrrrgh Got my card a few days ago and have been spending. Did you get yours Gemma?
