Worthless to inform you that your appointment has been rescheduled! Must go to orthopedics! Has now been moved about 6 to 7 times, of which I have reported 2 times for the cat's violin in hospital for an appointment! The agreements have been rescheduled twice without properly informing me. First time mistake in appointment I was a day late! Desk employee was unfriendly and told me I had received an email. I asked that she should show it? Then red cheeks! When I had another phone call from a colleague who had clearly reported wrong, she apologized that they are only human. I have accepted. But now 2x that doesn't make you feel good. Monday I was called, that may be true, but because I am a professional driver I do not answer a phone while driving! E-mail was also sent again, she could not find it but was able to give the correct e-mail address.
When I got home there was a letter in my letterbox that the appointment had been rescheduled, well what do you do with that afterwards! What a mess there.
