What they advertise and how they treat clients do not match

I had a claim for the repair of my turbo.when I phoned in I was unsure about the costs to the repair work to be done will be covered by dotsure spoke to a consultant they say they only cover the turbo charger.Reading my policy I see that it says I am covered for repairs to a genuine turbo fitted on my car . I put in a Claim for such, whenever you phone dotsure the lunes are forever busy, when need to speak to the relevant person handling a claim as stated you will never get ahold of the person.In cases of an emergency if I'm really stranded this company cannot follow through with how they advertise. My matter just seems ongoing from person being being long delay if answering telephone calls from the 28/092023 to date.
