Pearson Vue — Rescheduling / Cancellation of ISC2 Exam

I have contacted Pearson VUE for Rescheduling / Cancellation of my upcoming test from [protected]@ on 14th September because due Pandemic I am not able to travel test location in different state and in my state (mentioned in the address) there is no test center for the particular exam.
I was not able to reschedule the exam as ISC2 suddenly change their policy that exam has to be taken with 365 days, this rule came after my booking and also it was not intimated to me by any of the party (mainly Pearson as exam delivery related responsibility is in their part).
After many verifications and communications they were agreed to me provide the full refund in different card (I have closed the old card with account already) thru email and asked me to contact their support staff thru phone call but their support call denied that and asked me to drop an email asking for reschedule so that they can coordinate with ISC2 for rescheduling option and I did the same. Meanwhile I received another email from them where they asked me if I can get an email from the Pearson where they asked me to provide an email where card vendor mentioned that they can not open new account linked with old account. I contacted with card vendor and got the email confirmation for the same as well as I provided the URL from the card company's website only the card company presently restricted with some specific RBI guidelines and they can not open a new account for card (customer care representative asked me to provide the link to Pearson). After spending much time on this when send the email again I got an email where they mentioned they will be reviewing the case as rare scenario. When called again next day their on-call customer care representative denying. The communication started in 14th September for the test schedule for 7th October if they did assure me they I would have taken some alternative solution but instead they haven't yet concluded where now the situation is I am not able to take the exam and get the refund. They are very slow and misguiding me as their emails says something and while call they say something. Also they sometime they don't strict to their SLA for replying email within 48 hours., because of their delay I mentally frustrated and also need the solution from the consumer court.
