This is not cost-cutting. Answers here need to be precise — where a report went wrong, where a refund stands. Writing is more accurate than talking. Every email is read and every email gets a reply.
Quick answers
How long does a refund take?
We reply and confirm within 2 business days. Once approved, the Merchant of Record returns the money to your original payment method; card refunds usually appear within 5–10 business days depending on your bank.
Can I get an invoice?
Yes. Every order is invoiced automatically by the Merchant of Record and the receipt is emailed after checkout. If the company name, tax ID or address needs correcting, send us the right details and we will have it reissued.
What if a question or a report looks wrong?
Tell us the test name and the question number, or which part of the report reads wrong. We take these seriously: the question banks are maintained continuously, not written once and abandoned.
