I just dealt with two of them today.
First one: I have a pre-order in place with the local mortuary/cemetary to hold a cremation service and niche for myself in the event of my death. I am making payments on it. I set it up, **IN PERSON** to be on a recurring automatic payment plan. For some reason that baffles even my account representative, their corporate payment processor has failed to properly bill me, and instead issued me a past due bill, and a late fee. I went in person **YET AGAIN**, provided **YET ANOTHER** voided check, and signed the paperwork to go on a recurring automated monthly payment plan, in front of my account representative. (which she was very apologetic over.) Maybe this time the bean counters will fucking get it right.
Second one: My long distance provider decided that they wanted to suddenly pretend it is 1960, and stop all digital payment methods for their service, and accept only "check by mail" payment. I called their customer support number, informed them that I was cancelling services with them, told them exactly why (I'm sorry, but this is 2022, not 1960, and no, I will not be using 60 year old payment methods when much more expedient, safer, and more reliable means of making payment are readily possible in the modern era), confirmed the total balance due, then pretended it was 1960 (just this once), then wrote them a check with the invoice number and the confirmed balance due, and mailed it.
