Zero communication after 7days of registering a claim

My name is Ongezwa Phillip and I have registered a claim with Auto & General on the 13th already but I'm still struggling with everything. Auto & General never once called or emailed me regarding my claim, I'm the one that's been and still calling after them, the only communication I got from them was an sms saying that I should provide a correct email address of which I did and is still the same as all these years but when I call and ask what email address they have, they give me the exact same one. I'm supposed to take my car in for repairs, after calling them before 9am this morning, I'm still sitting with no hired car. Auto & General first said I must call Europcar after 2 hours, when I did that Europcar said that there was nothing booked for me by my insurance, when I call them back Auto & General said that they made a mistake it was supposed to be Avis and that they're putting me through to Avis, when speaking to Avis I'm asked questions that I don't know how to reply to and Avis consultant was shocked that they don't book the vehicle on my behalf as they should. I then again for the fourth time called Auto & General, after holding for more than 5 minutes they want me to wait till tomorrow for a rental car and when I said no, they again put me on hold and later just hung up on me and still no communication from them till now. My entire day is wasted and still no resolution to these issues and I know again that I'm the one that's supposed to call them back again, at this point I'm beyond frustrated, it's appalling how I'm treated here and I doubt I'd be staying further.
