Double debit for 1 item purchased........

On 16th May 2020, We called AA come assist us with a battery. when the driver arrived, a new battery was installed into the car and an invoice was done on the receipt book. My problem start where his card machine didnt authorise payment on the initial card and managed to work on the alternate card. This means that AA debited him 2 times for one battery. (ref186). He called 3 times already and a supervisor is supposed to get back to him on every attempt to resolve the 2nd of the debit

2nd -
