Okay. My whatsapp is going to expire on the 22/07/15 very soon, im using a iphone 5s..fully updated..but…. all of the 'purchase extension' buttons say 'N/A' meaning not avaliable (i think). How can i extend it? I know you can delete then reinstall but im in fear my chats will delete.. i have my chat backup on but still worried. So how can i extend it and make sure my chats are still there and not deleted? I have VERY important things and messages on there that i really do not want to lose. Please help me. Thanks. Have a great day!
