What happens if I get an investigation? Am I at any danger?

It's part of their procedure to move forward with the claim.

The majority of Investigations have a successful outcome.

One last question, what should I look for in the terms and conditions?

In terms of this case, obviously their refund policy and what grounds a refund Is Issued.

Also, whether they cover Items lost In transit. For example, If you're boxing the company, check If they cover loss of goods. There's a lot more, but It's beyond the scope of this post to detail everything.
