"Disappointed with service we received"

Very disappointed about our visit to the hospitals a&e department today. We went as my 2 year old daughter who previously last week was rushed to the hospital by ambulance, for having convulsions and an infection where she was unconscious for 25 minutes. Today however after having a raging temp yesterday, showed up a rash covering her face, neck, ears and stomach along with her left eye becoming swollen. We understood once arriving that it was busy. The receptionist told me it looked like a 'viral rash' so it wasn't anything to worry about but would get someone to check anyway. However, 2 hours we had still not been seen. Even though all the children before us, and who came in after us as well as various adults had all been seen. I politely asked reception how long it would be as my daughter was starting to get hot and clearly bothered. Still baring in mind she is only 2 years old with an obvious rash, we were told we had to wait another half hour!!! Furious we sat back down to patiently wait. When low and behold within 1 minute we were called in. Coincidence?? Then to be told by the doctor that she had an allergic reaction to the antibiotics she was previously given after her convulsions (penicillin) as she had never had antibiotics before therefore were not aware of any allergies. Therefore after the service we received and how we were made to wait for over 2 hours and initially told by someone at reception that it looked like a 'viral rash' and to not worry... to then be told it's an allergic reaction has deeply upset me.
