Not going to AVIS again

Today on the 30th may 2018 I phoned avis call centre and was talking to a lady named elize or liz . She was not helpful at all ask me credit card number i told her I am kot confortable giving my credit card details on the phone. 2nd she ask give me your booking number unfortunately I didn't had because car was hired from my insurance. While I ask her to hold the line so I can check ony emails after 20 or 30 seconds lady cut the call .

How ruse is that . This is unacceptable to me . I am a customer and this not the way to treat us .we pay your salaries dear. I want their superiors to investigate the matter and tell me where I was wrong . Not going to AVIS AGAIN.....
