Hello plmurm,
I am sorry that you have had issues purchasing bonus points online and that when you called you did not get an answer from our associates. Based on your message I believe the issue is that your account is too new. According to our terms and conditions it states that your World of Hyatt account has to have been opened at least 60 days before you can purchase points. If you need any further assistance feel free to send us a private message with your account details.
Best Regards,
John
