Hi @clairemattock and welcome back.
It's been a while but it's great to see you again. The BTP-115c error code normally means the service hasn't been correctly set up on the network. If you send me in your details, I'll be able to help you with this. I'll drop you over a private message now so you can get in touch.
Cheers
David

Hi @clairemattock ,

David
