I purchased the questions but still they are asking again to purchase it when i click on Next button at the end of the question from home screen. Here is the order number Order: CH_STR_*******999. They are responding very lately via emails. There is no customer care number to call and solve the issue. I recommend don't investment on this site and it's a waste of time and money. And after purchasing i was able to login and in dashboard ti's showing exam link and when i click on it the questions are different and i reached out they are saying your purchase is not done. Please find attached proofs.
