Test in a language you don't understand, no servic

I've booked my Exam. Ready to write on the 27th of October. When I got to the test Center only to find out the Language of the test is in German. I don't understand German. I called the Testing Administrator Eric Kibuuka and told him I can't write this test hence the fact I don't understand German. Eric took me out of the test Center and he wrote an Incident report and gave me the number to follow up. I've phoned the call center and the person I've spoke to said I need to wait 24 hours so the exam can expire and then, they'll do either a refund or book the exam to the correct language. I phoned in today asking about the query and they recon me I need to book for the exam again and make the full payment. I've paid for something that I didn't even do the test. The person I've spoke to today said if the college booked my exam they will do a refund. But because I've booked it myself, there's no refund or resubmit my exam. I need to pay for this again in full. Where's the customer service in this? I did show up for the exam, but I didn't write it. Because the language I don't speak or write was given to me.
