Part of the issue of grasping all this is that we are dealing with Staycar on tix purchased by a grandaughter and issued in the parents' names. Throw in the online booking service and it all becomes pretty murky. An OBS is merely an "order taker" so when someone contacts them about an issue, they'll just rattle off whatever they want to say to get the caller off the phone. I wouldn't be a bit surprised if this OBS does charge more for tix purchased with a credit. I don't even want to ask if the names on the tix are exactly the same as the names on their IDs. Such a lovely gesture by the grandaughter and so difficult to sort it all out.
