Deemed retirement under CCS rule 48A

I am an autonimous org's employee posted at Mumbai since 2017. Successfully served my organisation till march 2020 at Mumbai followed by stucking at Ghaziabad during leave (hometown LTC) due to lockdown. Worked from home upto July 2020 followed by putting up VRS, with more than 24 years of qualifying service, in Aug / Sep 2020 (from Ghaziabad itself) as I was unable to join at Mumbai as per office's advice. The office not only stopped my salary since Sep 2020 but also didn't communicate about the VRS. Recently in Jan 2021, again received a notice to join immediately at Mumbai to which I agreed to with the condition to relieve me the same day in view of rule 48A. Am I correct to accept their advice of joining despite the fact that I have become deemed retired under rule 48A (and hence joining not required) which mentions that the employer has to refuse the VRS in case of its non acceptance before the expiry period of the notice which was not followed in my case resulting in its acceptance at their end (and hence the assertion of deemed retirement). In fact, I had dropoed 12 reminders to know the status of my VRS to which they didn't say a single word even! Is there any technical fault in my approach? Some unconfirmed sources say that the reason behind their silence was that my vrs was conditional (as I had expressed my inability to serve the organisation at outside location in it), I was not physically present in the office at the time of issue of notice etc. I am of the firm opinion thay they were bound to reject my vrs under rule 48A even if the above circumstances prevailed. Is there any other rule which renders rule 48A ineffective? Can I take a legal recourse and is there any chance of getting relief on the front of my retirement benefits?
