I’m having the same problem, I’ve been going through the Cardiff clinic. When I say my PC she said the same about how I need to book ASAP as my surgeon is very popular. She’s always been really friendly in person and told me to message and call her whenever if have any questions, yet I tried phoning 3 times and no answer or call back, I also text and didn’t get a reply either. In the end I just rang the clinic itself to get an answer from someone x
