perhaps now he has been laid up, and with all the problems this has caused, he will be more open to accepting more modern and convenient methods eg direct debit, at least for council tax, as that is so vital, and no quibbling over sum owed.
i had an elderly relative who would not consider anything i suggested, almost on principle, as if i was an infant or untrustworthy.
but when that nice lady at the town hall said it would be a good idea...
similarly with getting a joint account, nice lady at branch set it up, but elder would only agree to joint signatory being someone who did very little for/ with them.
luckily that someone, wishing to continue hands-off involvement, was willing to give me the debit card, which i used in their name, all on behalf of elder.
sometimes you have to go all around the wrekin !
