Re: I can't make or receive calls or get ring tone.
Welcome you to the community!
I'm sorry to learn that you've been having trouble with your landline service.
Looking at things from here, I can see that you were able to get through to our helpline and book an engineer visit. It'd be great to hear back from you once the engineer has been so we know once your landline has been restored.
In the meantime, please let us know if there's anything else you need from us.
