TDS mistakenly paid fully by 1 owner instead of all 3

My parents and i bought an under construction property in Mumbai on 31 Mar 22 (registration date) and the builder paid TDS to the Govt in one owners name only on full value of consideration and not installment amount. It was mistakenly communicated to us one year later that builder had not deducted/paid TDS and 3 of us then paid TDS+interest+penalty on amounts paid till then. Few days later the builder comes back saying TDS was decucted and paid in one name and on full value of agreement and that we should apply for refund. What we did after that is tell the Assessment Officer (AO) that amount due to the Govt was paid on time (but mistakenly paid in one name) and then we paid additional amounts between 3 of us incl interest and penalty (say Amount X, Y, Z from 3 accounts) ... now they should refund X, Y, Z to us. We have already made 2 attempts on this but failed to get the AO to approve and clear the amounts. He has just asked us to make another application. I don't understand what to do differently to get this to go through.
