ICAI — Want refund

I have made a double payment to icai for CA foundation registration because when I made a first payment it was successfully reduced from my account but my form was not showing that payment was successful. Then after inquiries icai executer said that we haven't received any payment From your side I have made Second payment to full fill the form because they said if you made a first payment then your money of first payment will be refunded after making second payment . But 19 days are passed there is no any refund made by icai. I need my money back because I belong to middle class family my father's monthly income is only 10000 and that is also not with us because it was used for my registration.
