I have taken MCHA exam on 18th Aug 2015, but did not clear it. Received a assessment email from "email@example.com" , stating that " i may also benefit from purchasing a retake voucher. A retake voucher may be purchased for $100 by contacting firstname.lastname@example.org." there was no time limit mentioned in the mail
Now after 6 months, i want to retake the MCHA exam, sent a mail to "email@example.com", asking for voucher to retake the exam,but no reply.
Kindly help me in retaking the MCHA exam.
