As a few people have said, real, generally reliable service costs money.
One of the biggest costs in anything that may require human intervention is the human - and that's one of the things that tends to get put low on the list of priorities for cheaper services as hardware is a nice fixed cost, bandwidth can be bought cheaply (depending on where you are), and the YTS lad can reboot the cheap servers at night...
Having sufficient experienced staff available at all hours of the day/night, every day tends to cost a lot, and that is one of the things that you can pay a premium for.
