Is there any update on bahria tower karachi at tariq road?

I paid rs.75000 each 2 years ago to book two in bahria tower karachi which is on tariq road but after that there has been no update.

When will they issue installment plan? Someone told me that bahria has already issued installment plan and i received it on whatsapp but there has been no official communication from bahria in this regard.

Does anyone know about it? Are those rs.75000 i paid refundable?
