I've had similar recently in terms of both the "lurgy" and having to deal with "stuff" for my 98 year old mum (going deaf and blind but wanting to live "independently"!).
It will get better but these conglomerates don't make things easy! My recent run-ins have been with British Telecom, British Gas and our bank (all of which, we have been loyal customers for years!). Their system does not allow folks with any kind of impairments to access help. Even when you get through on a phone line, you are faced with menus, sub menus, call queues and then "I'll just pop you on hold whilst I look into the details"!
Customer "service"? Customer swervish more like. Don't get me started on trying to get a medical appointment!
My rant over too! Keep smiling and carry on!
