Idp Ielts — I was deceived !

I registered for my IELTS exam on the 24th of June, and I got a notification from my University saying that I need to submit language requirement documents by the 8th of July. I called Idp customer service and they told me that since I'm cancelling within 24 hours of registering there would be no deduction and I will recieve a full refund. I called again when I wasn't able to cancel via my portal. It kept on showing an error saying " Payment not reconciled, try again later". This went on and when I called again the agent provided an email ID and told me this would be considered as 24 hours since I have requested on mail. Now, today I received a mail for the email I sent on 25th saying I will only receive 75%. What sort of scam is this? And they mailed me at 22:12 and if I had slept like usual I wouldn't have seen the mail and the mail said " submit by today" !! I am attaching the call records where I called multiple times to verify the full refund information, you can check the records. In between I talked to a girl (the third call I made) who was in fact very rude. Others were polite and helpful. My ticket number for reference
