BPTP — Fitout and Handover delay

BPTP is not providing Handover of Flat in park generation on time. every time fake promise done by BPTP of handover. Next week and again next week.always a dialog provided by BPTP rather than a handover of flat. Workers always complain regarding material and funds but tell me how the client is responsible for all this who paid all his hard-earned money. It's getting worst and worst.
