Can't access my yahoo account through account key

Hello,



I cannot access my yahoo account. I used to access it through account key from the yahoo application installed in my mobile phone. I deleted it accidentally. When I tried to login from my desktop PC, I answered the first security question right. When I answer the second security question it didn't recognize it. I tried different versions (just changing one letter because in my language there are 2 different types of "e") but it don't recognize it. I have opened a new account, but since I have everything in my old one for years now, I retried to access it using my phone number (I don't have another backup email). But it links my phone number with the new email address. What can I do?
