Paid for a Mathcad Prime Student Edition via Cleverbridge, Received Product Key but PTC Website Denied Access, Cleverbridge of No Help and PTC is Unreachable

I am a student  and ordered Mathcad Prime 12 Student Edition. I verified that my credit union account was charged. I followed all of the linked steps in the email I received and got an error message: Access denied - Insufficient Privileges Our records indicate that your company does not have a current PTC Global Support agreement I have phoned and emailed Cleverbridge and have not had any luck in getting them to fix this issue. They incorrectly believe I have a billing problem which I do not! I am unable to speak to anyone at PTC about this because of the logic of your automated phone answering service.
