Компенсація за затримку або скасування рейсу Royal Jordanian Airlines

I received an email, offering me a voucher for €154.06 on 23rd April 2020. 5 days later, I received an automated receipt that was very ambiguous. The above amount was not on the document. Instead, there were various other figures of less amounts. On this document, it said "non-refundable" at the top and the information was at odds with the previous correspondence from the airline with the offer of €154.06 just days earlier. I emailed Royal Jordanian airlines back, asking how I am supposed to redeem my promised EMD voucher and what does this document even mean. I heard nothing and that has been unusual because there was an initial correspondence about sorting this out very efficiently. Perhaps they realised that they were making excessive loss. I am just dissatisfied because a company shouldn't offer a refund voucher and then not follow through with the decision. I simply want my money refunded onto my card.
