Rock Trading has no reputation here in the forum. 99.99% of members in this forum have never heard of it and the very few of us that are familiar with it associate the brand with a scam and will never use it and will never recommend it to anybody.

The best thing you can do to win the moral high ground and start the process of repairing the damage to the brand name is to return the money to the OP.
