More details about this: "I would want the option to give money as "thanks" to the customer, not only a gift card." – the most valuable people to get feedback from, are the ones who abandoned the service? They are not likely to be interested in a gift card, ... they don't want to use the service any more, right. But if you pay them money, then they might have time for a phone call with you. Or, if you send them an email, and ask what problems they found with the service — and tell them that the reason you're asking is that you want to fix the problems. So that maybe some day in the future, the service will be sth they will want to use. That can also motivate them. (But, I think, not enough for scheduling a phone call. Only to write a brief email back to you.)
