sadly the banks are forcing us all at a horrifyingly past pace into cashless society. We can no longer pay cash into anyone else's bank account - because it is not traceable - and i surmise that by the end of 2020 there will be no cheques of any sort any where in UK.
But for a charity to adopt such a dismissive and rude stance when offered a lot of money is something i would be very angry about also.
i have changed the charities i support in recent years and from now on will be supporting homeless organisations which are local and small and less likely to have huge salaries and over inflated marketing budgets.
Dont let your understandable rage allow the needy recipients of your money to suffer because of a "system" change......
