Type of education in WES canada application wrong

I have made a mistake while applying for ECA. Instead of selecting University Education under TYPE OF EDUCATION, I have selected Professional Education. I have sent a mail to them regarding this but no proper response yet. Is there anyone who has resolved the same issue or is there any other way around the issue that i can try?. Please let me know how to proceed further.

The reason i want to change the type of education is the difference in the required documents to be submitted for Professional education. For professional education we have to produce Certificate of membership document other than degree and transcripts.
