Duplicate transaction

i Went to fill up my car and i used my credit card,i put my pin and the transcaction was approved on my phone before i leave the attedant told me that the machine is frozen that means the transaction didnt go through.

I was late for work and i had to wait for another 10 minutes.I asked him to leave my numbers as i normally pass by in case the is problem but he did not want to listen he took my card swipped but the funny part was the second transaction was different amount.

I was late and i had to pay twice but no one listen to me.
