Need a quieter way to handle bills after my mum's hospital stay

Hi all, I’m posting on behalf of my mum because she’s not great with phone calls at the moment. She’s in recovery after a hospital stay and has been getting stressed about the Nexora bills and letters. Is there a way to note the account so staff know to speak slowly and maybe not push upgrades? We’re not looking for anything special, just a bit of patience and maybe paper bills if needed. I can help if someone tells me what to do, but I don’t want to make a mess of it.
