Xrbia — Delay in possession of my flat in xrbia neral k6-601

Address:

thane

Dear sir,
I am having following questions
1. if I suppose the possession date is march 2020 as per the agreement, if I add 18 months to this date it comes to Sept 21, then on which basis you are saying the date is march 23 ???
2. why your staff Mamta didn't respond to my mail and after that 6 reminders ???
3. why xrbia didn't inform the customers about the change in the possession date by mail, call, or letter ???
4. what amount of interest xrbia will pay to me for this delay and how their calculation will be ???
5. what amount i will get as interest + my paid amount if I cancel the booking due to a delay from xrbia in giving possession ???
6. what will be the exact date of my possession that you are offering including all the amenities like bus, clubhouse, etc ???
7. and lastly what is the exact reason behind this delay ???

I hope you will reply to the mail by tomorrow evening and you will not delay this also as you delayed in mailing me your first mail.
also, i would like to know what action xrbia will take against their non-cooperative and arrogant staff like Mamta for harassing the customer ???
