Spett. Wizz Air Hungary Zrt, Sono titolare del UD8FQF per il volo Wizz Air del 13 April 2023 da KEF Islanda a WAW Poland. I have tried to contact you thought contact form at site Wizzair (see CASE UID:1c877bd6??????? PNR:UD8FQF [ ref:_00D1tDYrQ._5003X2lDFsh:ref ]Unfortunately, your answer cannot be accepted by me and i must to go through legal way. As tickets were purchased from Italian Tax Number, I must to call you in Italian court to resolve this issue. I repeat the problem. We had a flight from KEF to WAW. I've tried to make a check-in online (by application). The App of Wizz Air shown me that its not possible to make check in. and its written Check-in not available. You have an overpaid payment. Please contact with the call center. I have done a screenshot. I've tried to done check-in 6 hours before departure. First, I was in trip in mountains and I had no possibilities to call. Second, a call to Wizz Air is a toll-call and I cannot understand why i must call to Wizz Air. Third, an overpaid payment means that Wizz Air has a debit with me. So Wizz Air have to pay me for something (and its not clear for what. Fourth, If Wizz Air have to payment me something, why you ban me to do check-in? As for me the situation is clear: it was an internal error in system of Wizz Air that due to my credit has blocked me a check in. So I cannot understand why you insist to avoid responsibility and reimburse me these illegal expenses that i will spend with flights with Wizz Air? We all loose time for nothing and are going to the Court just for an error in informatic system of WizzAir. Con la presente richiedo pertanto il risarcimento di tutti i danni subiti, da stimarsi complessivamente in 180 € (45euro for 4 persons) (780 PLN). Vi invito a corrispondermi quanto prima tale somma tramite riaccredito sul mezzo di pagamento utilizzato per il pagamento. In mancanza di un riscontro entro 15 giorni dal ricevimento della presente, mi riservo di adire le vie legali a tutela dei miei diritti. In fede, Voronin Evgeny
