Debitted my account

Good day, <br> On the 10th of August I returned a vehicle that I hired at Cape town international. The car was returned at 12:15<br> I filled up the tank for an amount of R344 at the Sasol across from the airport (not sure about the cents)<br> When I returned the car, it was checked that the tank was full!!!!<br> On the 14 August I was debited for an amount of R222,13 by Thrifty<br> I really don't understand this, I don't have the petrol slip anymore because it was left in the car!!! If I need to, I will request the slip again from the sasol garage across the airport.<br> This is ridiculous because before my account was debited, I should of received a call from Thrifty if the car was no filled up, which was impossible because I returned it with a full tank.<br> This is ***** and *******.<br>
