Continuity in service and counting of past service

Dear Sir/Madam, I want to put forward my case for views from your end. 1. I served in a state Govt. University as a permanent Assistant Professor in Dept.of Physical Education from 01.09.2010 to 29.09. 2013 before getting selected as a Assistant Professor (Dept.of Physical Education) in one of the Foreign University which I joined on 01.10.2013 after resigning (technical) from the Indian University. I went through proper channel. There was a Break of one day because it took me one day to reach Abroad and join. The Salary I was getting is as per UGC Scale. My Ph.D has been awarded in 2011. 2. I worked in Foreign University from 01.10.2013 to 21.07.2013 3. Now again I had been selected as Assistant Professor (Dept.of Physical Education) in one of the Indian Central University. I joined on 25th July 2015. Again there was a break of 3 days This break may be treated as joining/journey/technical period break because it was also a fresh appointment and I was leaving from Abroad permanently so I have to submit my residential permit and get an Exit VISA to enter India, for which I had bound to wait there for three days to get the official work done. So, I joined this esteemed university on 25th July 2015 F.N. I also came through proper channel. The salary I was getting is fixed in US Dollar. 4. Everything went smoothly. But now when I applied for my next promotion through CAS of the UGC, an officer is objecting to the counting of my past service saying there is a break because I had resigned from Parent University and joined other university. 5. Till date my total teaching experience is since 01.09.2010 onwards 6 years 5 months. And I shall be promoted to next grade pay i.e 7000. 6. Also suggest me how can I protect my salary because here I am getting my initial salary. I will be grateful to you all.
