Miscommunication and accessibility concerns

I'm new to arranging 'meet & greets' at airport parking lots, and I tend to get easily lost. For my last trip, I asked for specific instructions to deliver and collect the vehicle, but there were miscommunications both times. Despite this, I booked with them again for a new trip, thinking that at least now I knew their exact location, However, they informed me that my flight was too late in the evening for them to assist, which was disappointing since their website didn't mention any time restrictions. Additionally, I'm frustrated that they continue to send voice notes via WhatsApp without asking me beforehand if that’s okay, since I have a hearing impairment. Lots of things on this company just scream UNPROFESSIONAL
