Osmania University — I'm complaining about staff behavior of academic block

I submitted the request for getting equivalence certificate from ou for my pg as i moved from anna university, chennai. Last 15th oct came to initiate the process. They made us wait for 1hour for their lunch. And the staffs behaviour is very worst towards the aprroaching candidates. They were treating them in an irrespective way and very very dominant. I haven't seen this kinda approach in any university. Again i came today at 2.45pm and entered into the academic branch and shown the receipt. After me they closed the door for lunch break as few more people waiting outside. They insisted me to come after 3 in order to finish their lunch. And they are very rude. Candidate who are approaching them are not just slavery people and they are obviously not a king. Its a service what they are doing. They have to give respect and take respect fron us. Seriously pissed off by their actions. I don't appreciate this waiting hour of 1.30hrs as they could complete it in 5mins. Kindly provide them some criteria how to treat with the candidates
