Claim process & outcome

On the 6th July i was in a car accident it was my very first experience i was shaking and shocked, i called IWYZE until i ran out of airtime. I finally managed to log a claim *** via an IWyze Hub and requested a callback. The communication has been terrible poor having to call and follow up with them, They finally appointed an assessor where i was requested to send images which i did. The last call i received on updated was on the 17/07/21 that they are writing off the car as it is UNECONOMICAL according to them, and how i will not be getting any replacement car as they only start on model 2018 to replace mine is 2017 and on the Policy documents nothing is mentioned about the model years on replacement . I have been trying to call for a cancellation and sent an email to cancel the claim and the cover no response yet. lWYZE isn't giving any peace of mind it gives stress from day 1, im travelling to work using public transport because the hired car needed a deposit and someone was to call and confirm and no one did. I regret dropping my previous insurance because someone recommended them ?
