Andhra University — Not respond to phone call

I have applied for PC and submitted required fee and documents by hand at University superintendent office and they told that they will send in 4-5 days. If not sent provided a contract number for assistance. After one week I have called them and they told me to contact the next day. Since then they are not answering phones at all. Yesterday called 10 times and today 24times without any response ([protected]). Please check
