"I will forget the bill" 
. Why ?
We have a magnetic board to hang bills upon as well as a calendar to write important reminders on.
Our dental surgery will ask for payment up front for a) new patients and b) for any that don't turn up. It is necessary to ring and cancel if 1 can't attend GP/Dental appts..
With every1 relying upon mobile phone apps it should be OK to put reminders on - me, I can't work an app 
so have to remember to keep our His/Hers calendar up to date 
However: I have had brain fog recently
thanks, I'm pretty sure I cancelled on those occasions though and pretty sure it was two, spaced well apart. they have lost two members of staff, they just don't need me asking for an appointment.
I tend to be of the view that if you call to sort something out you should be able to most of the time and it might just be where I live at the moment but it's impossible, every single day. 5 attempts to sort a GP appointment, I only want some estriol cream, I asked if I could send a message but no. I might be old school but I do expect to be able to contact a GP surgery and make an appointment
I will forget the bill because it's a one off thing, not a regular electric or gas etc, and if I attempt to deal with it and can't it will get forgotten, there's loads of other things to deal with and coming in all the time, but I'm still working. If I could use my card to draw out money or, well, just use it, I'd drive to the place and pay the bill straight away, but can't do that because card been cancelled, can't go to the bank to draw out the money because the branch closed in my area and it was 2.30pm when all this was going on so too late to drive to another area, because they close (in my book) half way through the day.
