Please, Do NOT Book Anything From Sunweb. A 6800€ travel package from Sunweb was cancelled due to COVID-19. As they refused to refund, I submitted a chargeback request by my creditcard bank. Sunweb then issued the socalled Corona Voucher to me, stating that a refund is only possible after 1st November. Yet the voucher is marked as "VOID" and can not be used, the reason, according to Sunweb, being that I have requested a chargeback. Sunweb then went to dispute my chargeback and won. My credit card bank rejected my request, Sunweb kept the money. Yet the voucher is still "void", THREE months since the chargeback has been settled. I contacted the customer service to ask them remove the void tag. Firstly they say they just need the confirmation letter from my bank that the chargeback has been rejected to re-validate my voucher, which I provided. Then, after another month, when I asked again why the voucher is still void, they say that they need a direct confirmation from "ATOS/Wordline"[sic], which I have heard of and was never mentioned by Sunweb before. And I have to contact this "ATOS/Wordline" by myself, they do not know when the confirmation would come, if it would come at all. It is not my responsibility to chase some third party to get my own money back. Just make sure this never happen to you, guys. Avoid Sunweb as you would avoid robbery.
