Kpn Travels — KPN travels - ticket booking issue

I recently booked a ticket from CHN to CBE via KPN travels app. I have neither received an E-ticket nor an email or text confirmation regarding my journey. I am not able to cancel my ticket, since the website says the given boarding pass number is not valid and I am not able to log in into their app. I tried reaching around 10 to 12 numbers of their offices and branches. None of the number is in service. Kindly guide me with me and help me to get my money back.
