Claim authorisation

I am an Iwyze insurance client.I lodged a claim on the 29.04.22 after an incident of hitting a pothole (2 tyres and rims damaged).To date Iwyze hasn't given an authorisation number.They don't communicate despite me requesting a call back from their app several times. I've tried calling them several times and in all occasions I wait to be assisted for over an hour until I hang up. I have sent e-mails to several email addresses for assistance with no response
