Extra payment not advertised

I see alot of similar complaints like mine on hello peter im sure il get back up if I report this and make it go viral. Next time advertise on groupon extra payment for exam coz it was Def not advertised as is when I bought and redeemed vouchers last year. I would not have bought it then I can report it to ombudsman for false advertising. I did alot of courses before and I didn't have to pay now after I bought 3 more I had to pay for exam. I refuse to pay extra for exam so I want my money back or free exam for 2 courses I got left u will refund groupon voucher and my data wasted on webinars and assignments. I feel everyone who bought the groupons before new rule deserve money back or free exam and ur next advertising should state pay for exam or il put in a compla I nt with ombudsman. They can teach u in course about advertising but see how they advertise.
