Don't accuse your customers of *****!!

On 21st oct we hired a car for 16 days,we also requested a Toyota Avanza and it's on our conformation voucher,upon arriving at Avis we obviously disrupted your ladies tea party with the way we were treated! We were told there's no avanzas so we must take a corolla,we produced the conformation voucher and were shouted at by Tumi saying we together with our travel agent committed ***** on the voucher! The Indian male manager agreed!! Does Avis give vouchers to everyone I wonder!? Upon leaving in the corolla we faced a blow out outside Etetwa off ramp on our way to Witbank,I called the emergency hot line. 30mins later they called me back and said I must have R10k waiting for a Mercedes Benz as they have no other cars!! I said no I simply want the tyre changed,45mins later they call me and say the charge is R600. Bu this time I was sitting on the side of the road for over an hour with my baby!!! They never did come. We had two blow outs in two weeks because every single tyre was a different brand!!! Avis you disgust me, your staff are rude,arrogant and unhelpful!
