"Sons accident"

My son had the misfortune to be hit by a taxi in Birmingham (illegal manouvre. ) He hurt his clavical ( broke in four places). Upon getting to the hospital he was left in a corridor half naked, dismissed as non urgent as three staff that dealt with him didn't even know he was in a road traffic accident, one staff member told him to get out of the wheelchair he was in, until he mentioned he was in a road accident. at no time was he xrayed scanned etc until he mentioned this dispaite having cuts to hit head. I understand the pressure of an A & e ward however my son was still in shock and was ignored and given no blanket to cover up with , no drink, no care and attention. The nurse gave him a sling on the way out and even that was fitted incorrectly across his collar bone. Disgraceful
