Lack of Customer Service

I hired a car & collected it after hours at the OR Tambo Branch, was assisted by an Avis agent & not a Budget agent. The agent did not take me to the car & do the standard checks, just handed me the keys & told me where to find the car. An Avis agent checked me in on my return & pointed out that there was hail damage on the roof, which was there before but as no one had checked the car when it was rented out it was not noted. Please note that there was NO hail fall in the time that we rented the car. On my return I received an SMS advising me of the claim for damages, I called the number & queried the claim & noted a dispute to the claim, the agent said that he would lodge the claim, that I would be copied in on the email & would receive correspondence from the offices regarding the claim. To this date I have received one email advising that the department would be investigated but other than that no correspondence or calls from either Budget or Avis, no invoicing (which was requested) detailing the amount deducted from our account & no feedback on the dispute of the claim. Emails are not answered and calls to the call center are not answered. Feeling ******!!
