Since you only have 2 reviews, you are seen as a newbie. With that said if a provider blacklisted you then most of the time there were good reasons to do so...such as, trying to take the condom off...trying things that are not on the menu...thats just a few reasons...
If you did nothing wrong...which is possible...although there are many reasons why you could have been blacklisted...then you should try to apologize even though you feel you are not wrong...it is better to be proactive by trying to fix the situation than make the provider even more angry and escalating it.
