I had a question for a lawyer. The lawyer who responded wrote that he would get someone familiar with that bit of law to talk to me, that there was no need for me to respond. I rated him highly, and I found out rating effectively seals your credit card payment and ends the conversation. Just answer refunded my money though, and I will try them again in future.
Maybe someone could work on the website to clarify more about how to continue a conversation until an answer is delivered.
