Lodha Group — About multilevel parking given at time of booking and suddenly changed to open parking after 2 years .

I am Dr Dipankar Chaudhari, owner of flat Primia I 1202, Have been alloted closed parking ( multilevel parking) at time of buying this flat and this was the reason we bought this flat . We were promised and also given the parking . My parking number is C1-B2207 as per the letter we received . It is in multilevel parking area near our society .
But suddenly after 2 years they have changed to open parking without any info . I have booked this flat only because it was closed multilevel parking . I request Pcma and Lodha group to kindly retain my old parking as per my letter given at time of booking .
I am writing this complaint because no one is responding, including Pcma since long .
