Unprofessional service from Avis

I got a call at 18:37 from a *** number on the 27th of May 2024 from your collection desk claiming that I didn’t make a payment that I owe you Avis, I calmly asked the agent where did he get my information because I don’t owe you guys a cent and asked for a statement, he told me to wait as he is spending my statement showing I am paying monthly, he couldn’t answer me that. okay I asked to speak to a supervisor which he said his out. I want to know Avis do your guys call at that time of the evening. I want to find out how my information was leaked and why do you guys say I owe you this will have to go to the ombudsman as it will massively impact my credit score. I’ll wait for your respond and I want this sorted out soon or you will hear from my lawyers as this will be the start of my ID being compromised.
