Apollo Hospital — allocating wrong room

Address:

Gandhinagar, Gujarat, 382424

My grandfather was admitted 3 days ago. He is an ONGC employee and he was alloted a Single ac room. But the hospital gave us a double bed room. They are going to make a bill of single ac room. My grandfather is facing inconvenience there.
Some of the staff is also not professional, they send nurses who doesn't have experience. One example is when a nurse came to take blood sample and spilled blood all over bed.
