humiliated and no communication

I went to gym this afternoon only to be told I can't enter as payment has not been made.which I was unaware of because it's a debit order.i had to renew my bank card this month and only now told by counter staff that Vigin requires me to update details. 22 days into the month, this is the first I hear of this.and none of my other debit orders require an update.so the guy behind the counter say I can phone head office to give new details and make payment, which I could not as I am in a big rush in the afternoon. The correct way to handle the situation would have been to let me enter the gym and then head office contact me the next day for update, as they the ones who require the update, which I was unaware off. After being humiliated at the front counter I think I won't update anything and rather start a new contract at the new cheaper gym up the road.
