Dealfind Voucher not working

Hi everybody!
I bought a ling-voucher on In the mail it says, that you just have to enter the code on the bottom and then you can start with the programme. Acutally there is no code, unless it´s not the “T B 0…”-Code above, but this doesnt´t work as well. Any help?

@keyexx - If you have questions about deal coupons, please email and include your voucher information.
