In the SMS, it is asked to fill up some data which would be useful my consulation for doctor.
When I click the link given, I do not see any appointment nor I am unable to fill up any informanation as required, as I am not prompted to do so. I have been trying to contact your hospital Greams Road Customer Enq using both the numbers[protected]/[protected] for connecting Appollo247 but N number of attempts to give connections go in vain and I am not connected. Tomorrow being appointment and this is the first time for me to meet the doctor on online, I am helpless as to how to proceed
