Incorrectly debted and invoice

<p>I booked a vehicle via Rental Cars with Europcar on 17/01/2017. Payment was made and on collection day the voucher was provided to the attendee @ Lanceria Airport. When I received my invoice from them on the 25th I notice that I've been charged for the full cost again. The payment made upon booking was not deducted on their invoice. This was brought under their attention immediately with proof of the payment. I received a call the next day from Emma and after a 2nd conversation was advised that a dispute will be logged with the Accounts department and a revised invoice will be emailed to me. It’s almost 10 days later and still not correction or refund to my bank account and also no corrected invoice. This was an over deduction of R749,96 were I’m only liable for R346.67. This is ***** on the side of Europcar.</p>
