They don't show up for anyone normally on the phone. You have to be on a laptop or desktop to see them.
I used to get loads of complaints for pretending to be a qualified tradesperson which i thought was unreasonable complaints, then one day someone mentioned that it was because i hadn't added a signature. I had no idea they even existed until then.
Then fight back against the unreasonable complainers. If they, because of their stupidity or refusal to pay attention or febrile imaginations, were drawing incorrect inferences then they were the ones at fault.
