Hello there,
I have similar problem with cancelling my phone from abroad.
I live abroad now and need to cancel my Odido mobile subscription, unfrotunately I cannot reach the online cancellation form because it asks for second verification by sending 4 digit code to the mobile number but it never reached me anymore since my old tmobile sim card is now not working anymore.
I tried to make a phone call to 0800-0092 but half an hour I just hear music as all operators are busy.
Can someone from Odido please help me with this?
Thank you.
