I called RAC and was told to wait up to 90 minutes. After 105 minutes of no showing I called again to be told that my request had been cancelled by whoever and for whatever reason - he couldn't tell me. A new 'request' was logged and was told to wait another 90 minutes because that's what the system is set for. After about 60 minutes, a nice young mechanic arrived and changed my damaged wheel and was able to go home. I was in no danger, only bored - to death - as I didn't have anything to read in the car, not even my smartphone. All is well when it ends well, I suppose no one is perfect so this is it.
