I spoke to the team on the phone and they said they have no proof I came from that site. The website times out several times through the order though so I refreshed my browser. Happy to wait 90 days but just wanted to check there is a record of me using the link from broad band choices.
Ive no idea what order they issue the vouchers , bare in mind it is the Website that you used (BBChoices) who actually issue the Voucher , not us or Awin.
Might be worth dropping them an email,
