I am S Mangesh From Hyderabad,  I have booked Flat at Lodha Group CASA PARADISO, HYDERABAD in 2010.  which is still in under construction stage, Builder has promissed the deliver/position in Feb 2012 thats the reson I have booked this flat with Lodha group,  Now Builder has pushed the deliver / position tentatively in Jul 2012.  Inspite of delay from Builder site Builder is demanding Advace Service Tax on the amount which I have disbursed aroud 60%. 

Why should i pay the service Tax in advance to builder as i have not received the service i.e. position of my flat and also it is not sure when i am going to get the position.  In this view why should i pay service tax in advance to builder?

Please advice me on this at the earliest,  as this builder is charging 18% Interest on Late payment which is huge amount.

Thanks & Regards

Mangesh.
