Hey @Liz68,
Welcome to the community and thanks for taking the time to post your issue on the forums.
I'm sorry that your phone is still not working after being removed from the blacklist. I would be happy to investigate this further but to be able to look into and discuss your account further, I would need to take a few details via private message.
I will drop the message over, please look out for this and we can get started.
Regards,
Steven_L
