"Incompetent admin team"

Attended for an endoscopy procedure after limiting my holiday by having to go on a low residue diet for 4 days and take a bowel cleansing preparation, to be told the admin staff had not entered my appointment in the diary even though they sent me a letter to confirm the date and time and followed up with a call to confirm the date the Wednesday prior. Consequently I was asked to wait in the car (as per the entry procedures for endoscopy) on the hottest day recorded in the uk (40 degrees) without being able to drink any water. Whilst the clinical staff eventually recognised it was an admin error and went ahead with the procedure in a professional way, albeit rushed as it was an inconvenience to fit me in for them, this was 70 mins late during which time I felt extremely anxious and close to tears. Possibly as a consequence of all the upset or maybe the rushed timing for the team that had to fit me in, the procedure was significantly more painful than previous endoscopy’s . An apology was never offered. The administration at this practice needs a thorough investigation as it’s incompetent.
