They sale bad material. When you try to return, they encourage you to take the test or other versions of the material so that they produce ground excuses to not return your moneys, so don’t fall for this trap!!! | This is a very corrupt company, at least at supervisor levels. Their materials have many issues valid for anybody to lawfully and legitimately ask for a refund, but they just hang-up on you and don’t care; they transact through a third party company to make it more difficult, and have many domain names, web redirects and phone numbers to mask their abusive practices. Their supervisors are very rude and without real knowledge of their own products: they all try to avoid your valid questions at complaint, talk over you at a higher voice level to intimidate you and try their best to totally deviate the conversation, which is a common practice of fraudulent people. | Very dishonest business practice overall. You will loose your money. They are also listed with many issues on BBB. Stay away from them. Try other companies.
