Maggiore Car rental Italy credit card problems

For the past 2 years we have used Maggiore car rental services Italy for car hire whilst on holiday in Italy. They are associated with Avis car hire. Please be aware that for two consecutive years I have had unauthorised debits to my account from this company long after rental has been paid in full - to the point that I have reported the same to Absa ***** and had to change my credit card number twice. Last years unauthorised debits were returned to me by Absa I have searched the internet to try to find a customer care contact email for Maggiore without success. I am sure its not the company itself but there must be someone working there who is on to this credit card unauthorised transaction problem Be aware
