We put $20 onto it, and it worked fine for a month and a bit and is now out of credit. I popped the sim into an older phone which it would fit into, and reset the your 2degrees password to have a look online for it, shows that there is a carryover minute pack on hold because we are out of credit.
Texting stop 19carry to 233 got back an error "something's gone wrong" asking me to call 200. No pack is showing as active, but one is yellow whatever that means.

Friend is not impressed that the $20 is gone with barely any use, when it should have lasted ages at 9c per sms.
2 questions:
How to remove whatever pack is caused the $19 to disappear like that?
Any chance of getting it back since it was never actually added or used?
