Their referral program SUCKS!
I have joined their referral program and for weeks I am waiting to receive my referral bonus. I don't know where to begin, so many things were off and misleading or confusing:

1. Spend 30 EUR, get 30 EUR you said. My girlfriend spent 30 EUR, waited for a month to receive the card and all the trouble. but then in those small letters with terms of conditions of the program we see that she needs to spend 30 EUR AT ONCE. do a better wording next time can you?

2. ANother friend just booked his plane tickets with his new card. this happend 3 weeks ago. Bonus? Still pending, because their support people just keep saying 'It may take up to 60 days' to receive the bonus. 60 days? WHY???

3. Even though I am still waiting for 60 days to be completed for (hopefully) receiving my bonus, another friend of mine already did receive his bonus. Which is super annoying, seems like it is quite arbitrary, some receive bonus right away whereas the rules just apply for some others, apparently.

4. I contacted their support agents for a proper explanation and I don't really want to give into the details of the quality of their support agents. They are just a nightmare.
