iGame Casino - Refusing to credit Free Spins as promised

I recived a mail that said i would recive 70 spins on the slot Second Strike if i made a dep of 250 sek.
(copy from mail) Erbjudande: Få 70 Free Spins på Second Strike när du sätter in 250 Kr eller mer.
Insättningskod: STRIKE70
Tillgänglig till: 23:59 CET 4:e januari 2016

Now... i made a dep, and i wrote the code.
Then when i played my "real" money to zero i tried to open the slot Second Strike, but it didnt work, it didnt open. so i contacted Chatt that said i didnt!!! write the code, and the will not give me the spins. Fortunately ive been playing a while so i know when im right and not. In this case i PAYED for 70 spins that Igame dont want to give.... why not?
I usually take printscreens on this kind of deposits since it can be wrong, but this time i didnt since Igames codes allways works... but not this time and they wont take responsibility and fix this for me...
So Igames bonuscodes are not reliable.
