Parking not mention in sale deed

Hello Guys, Need help. I have purchased one property in April 2014. the registry of the property was done in Aug 2014. At the time of purchased, the builder said the flat with four-wheeler parking same has mentioned in the initial agreement as well. however, at the time registry ( sale deed) he changed the word from four to two. so now in registry its mentioned two-wheeler parking. Both the documents are submitted in the bank as I have taken the bank loan. Need suggestion? what are the options I have now? Thanks in advance for help
