Stuff can happen with anyone for any reason. Even reliable processors and service providers can have issues once in a while. So what you may want to do is sign-up with several processors and if you experience any problems that may take longer to fix than you are comfortable waiting for, plug-in one of your other processors until everything is fixed.
