Failed Booking Service

I made use of your Appointmed Service and everything seemed to be going great. It was so easy and smooth. Until I arrived for the appointment that was confirmed by SMS as well as email. Both said 24 November 2020 13h30. When I informed the receptionist that I am there for the above-mentioned appointment, he said that appointment is only for the 26th, and he can remember the conversation with the lady that made the booking. He was also surprised that I got an SMS, as their booking system doesn't send out an SMS... Now the appointment had to be rescheduled for the 3rd of December as I cannot take another day off work this week. Not to mention the transport fees all for nothing.
