Mahadev Complex
No receipt of maintenance payments

I bought the place two years ago, and moved in about a year and three month ago. According to the contract, I've paid a year's maintenance, like everyone else in the small complex had. And after a year, now when we're supposed to pay the maintenance, the builder would accept payment only by cash and won't even provide proper receipts. The only written document he submits is a torn sheet of paper with the amount and month written into it.

So, along with everyone else in Mahadev Complex, we've chosen not to pay the maintenance, until he doesn't come up with concrete receipts. The obvious reason for this is getting rebates in taxes.

Please guide the action in this case.

Thanks.
