Why cannot banks carry out this simply request for their savers, banks do not do much for savers nowadays. Banks have the facilities at their finger tips such as their money maket department, to perform this simple task for savers, instead they would rather loose their customers, which according to the media whcih is something they would want to hold onto.
My uncle would not want to use an account, as it would negate the very small amount of interest he may have accrued in interest that banks pay today. Therefore he would be far better served to withdraw his saving and put it into an account where there is no calculations to do be done, or a bank that is willing to look after him as well as his savings.
