Transfer fees (with GST) 90% paid by buyer, receipt issued to seller

I had bought a flat in Mumbai in Oct-21. As per agreement submitted to Society office the transfer fees of Rs.1,61,952 including 18%, GST will be paid equally by buyer and seller. The society office manager was the broker for seller. Further we mutually agreed verbally that only Rs. 12,500 tol be paid by seller & Rs.1,49,452 by me. After I moving into the flat, the society manager asked me to pay transfer charges, to which I asked him over email about the transfer charges amount, procedure, rulebook of society etc. He replied me with the breakup of the transfer amount alone. I paid the amount (the amount included 18% GST). After paying transfer charges, the 100% amount receipt was issued to seller, I had paid >90% amount. I had immediately raised the objection on this over email and asked society manager to issue the receipt on my name, which society did not agree on multiple occasions till August 2023, when they denied to issue any receipt on my name. Please help me.
