Why is it that on bank holidays buses can run through individual towns, but outlying estates are left busless?

If bank holidays fall on the weekend, there are no buses for three and four days. Pensioners and families with children, if they have no transport, are left housebound for days. Shops lose trade as well and if you wish to travel, you have to walk to the nearest town to get a bus. Surely a bus could be run on a Sunday service basis, although we don’t have a Sunday service? If you want to get anywhere, you have to walk a mile to get a bus. I worked on buses many years ago and we always ran at holiday time. They say we should use public transport, but it seems on weekdays only and not Sundays and bank holidays.
