Godrej — No Response from RM

I purchased two unit of godrej Avenues g204 & g1204.
I am trying to contact my RM since 1 week. Her phone is off. (Monika +[protected]
It was on for 10 minutes on 24th Feb and she was shouting & not agreeing that her phone was off.
I sent email and whatsapp messages and no response there as well.
I feel like buying godrej property has given me stress. I am already High BP patient and additional stress will kill me and godrej should be responsible for it.
I would like to cancel my unit and want my refund for both the units.
