Leaving ID with no SIM or other details, final demand received, unable to pay on app or automated line
I am trying to leave ID mobile but no longer have my SIM, phone number or any other details in order to access the app. I have tried to explain this several times to no avail. I have now received a final demand but the automated payment line will not accept my call. The letter was dated 13th July and i have received it today, 20th July. Please let me know how i sort this out?
