I am an existing (second contract) ID Mobile customer.
My wife and eldest daughter also joined recently (on my recommendation).
I decided to also move my youngest daughter (14) to ID and ordered her a SIM during the Black Friday sale.
This order was subsequently cancelled as I apparently failed an ‘internal security check’!
The algorithm for this is clearly flawed as this was a genuine purchase from an existing customer.
Needless to say, none of us will be renewing our contracts when they expire.
