wrongly diagnosis but not treated

my wife aged 35 years was admitted in a hospital for treatment. the doctors advised a test (diagnose) and refer a diagnosis centre for diagnose. the centre was wrongly diagnosed. the admitted hospital also wrongly diagnosed. basing on the wrong reports they are ready for operation before they going to operation they are explained things after the operation to me and my family members that the operation is a serious type and the patient may be died while operation or after some days later. then we are not believed the doctors. she ( patient) was shifted to the another hospital. they are clarified that the diagnosed reports are wrong. she (patient) has a small problem. they are done the small surgery now she is healthy. my question is, can i file a case in consumer court for compensation on both the hospital and diagnosis centre, for wrongly diagnosis and mental agony and hardship, OR not. please refer some cases its related.
