No response for confirmation

Customer service is absolutely disgusting. I am currently abroad and have booked one of your rentals online on the 25th of dec 2017. I have not received a confirmation email and I am trying to get confirmation that the rental is finalized. I have had no response for two weeks. Fair enough it was the festive season and I understand. I received a mail after a while asking for the pickup location of lanseria airport, but no response after. This is just pathetic now, it’s already the 7th of Jan. Is it that hard to say YES or NO, the booking is confirmed? I am not a first time user, and have rented cars from you before, but going forward I won’t be using the services of budget/ Avis again.
