Is this normal?

I would not judge only from the first WhatsApp message. My clinic was a little slow before booking but very organised once I asked for a written plan. Another clinic was charming and fast, but every answer was basically 'do not worry'. That made me worry more, honestly.

For me the quote was less important than the plan. I wanted to know who I would meet, which tests were included, and what would happen if swelling or pain felt unusual after flying home.

My English is also not perfect but I understand you. Ask who will answer after you go home. For me this was more important than hotel stars.
