Is Thrifty’s new partner, Sani, a ****??

On 9 October, I received an email from Sani car rental. They thanked me for taking their call and informed me that they are now partnered with Thrifty. I DID NOT SPEAK TO ANYONE. Then, on 26 October R400 went off my credit card for hiring a car from Sani. I HAVE NEVER HEARD OF THEM, nor have I been in contact with them. The bank says the payment was authorized with my CVV number. I had to cancel my credit card and open a ***** investigation. Is Thrifty selling out personal information??? I have hired cars from Thrifty in the past (but not in the last 8 months). My only explanation is that the details stored on Thrifty’s server is being made available to their new partners Sani. How else can my credit card be used and how can I be receiving emails of claimed communications when I have no knowledge of the new company’s existence. Very disconcerting…!
