presumably the blame attribution is done by the station person and then the look for a cab on a GWR▸ , TfW or XC▸ contract? Nightmare!
In my case, I informed TFW of the missed connection, told them there were no further trains today. He went into the office and phoned Crosscountry control, who asked for my name and mobile number, was told to wait for a text and wait in the short stay car park outside the station building. 5 minutes later I received a confirmation text from the taxi firm involved, the taxi arrived 15 minutes later, no questions asked and took us both to Pilning, we did have to guide him a little bit
