Hi MollyisMoon,
Thank you for your post and welcome to our community forums. We're here to help.
I'm incredibly sorry to hear that there's been some disputed charges on your billing recently regarding disputed landline calls being made. The late payment fee you're referring to sounds like a result of you cancelling the Direct Debit. We'd always advise against this as it can cause further complications, such as the late payment fee you've now incurred.
As for the additional disputed charges for the calls and what the technician has stated during their visit, we'll need to take a closer look at things. Please respond to the private message I'll be sending to you shortly when you can and we'll proceed from there with this.
Thanks,
