Sikkim Manipal University — sikkim manipal university delay in exams and only examination centre sikkim

I am in 5th semester and pursuing mca. I am from delhi and it is not possible for me to go to sikkim to give exams. The mistakes are from university end and we students have to suffer because of your mistakes and court cases.
I enrolled in sikkim manipal for mca as it has a centre in delhi and now u gave a message stating that exam will be conducted in sikkim, if we were interested in sikkim for exam then why we choose open university its better to study in local regular universities than going to sikkim for exam. Such behaviour is not acceptable. I am trying to contact at the help desk but there is no response or only saying that no other examination centre available.
Guide for every semester calls to help students up to 3rd semester and ask their queries but as we reach to 4th and 5th semester no one calls to take note of students or help for queries. Also after the change of location of exam centre also the guide appointed for the students should have called to help students but such help is also not provided from your end.. Just a message forwarded that give your preference month for the exam in sikkim.
Helpdesk is not responding to calls and giving messages that u have still not given your preference for the exam.
Kindly arrange for the same exam centres that were chosen at the time of admission in sikkim manipal university for already enrolled students.
Waiting for a positive response from your end.
