We are a senior citizen couple and we booked a slot today morning at 6.30 am for sample collection. The phlebologist ( sample collection guy) called at 6.30 am and informed us that he is giving the work to another guy . We called toll free number to complain. They said they will take min 30 minutes to tell us the solution. We had to cancel the booking. This is the second experience with 24/7 . They are absolutely undependable. Never book any sample collection with Apollo 24/7.
