OH dear AWYRCYMRY how to win friend's and influence people.
I know you and I have corresponded already by email at work ( yesterday) regarding visits and would suggest you take it up soonest. I'm sorry you think you had a raw deal, but a phone call after landing to find out exactly what happened is the best course of action in this instance.
You could of course asked the ATCO to say it more slowly for you, that wouldn't have been a problem. Perhaps when you do visit it will become more clear to you
