Dotsure and Hollard poor service and miscommunication

My policy was transferred from Hollard to Dotsure in July. I was never contacted telephonically to understand the ramifications of the transfer as still communicated with Hollard on policy issues. I had a mechanical break down on Saturday which Hollard authorized on condition that it would verify the claim as policy showed inactive. On follow up I was told Dotsure was the insurer and they should entertain the claim. Dotsure initially said they did not have my database and as such Hollard should handle it. Eventually, when I insisted on the release of the vehicle so that I could fix it for business purposes, I was told that I used the wrong service provider and should have AA. My concern with this is that I never appointed or authorized the towing but Hollard did and the issue of the service should be handled by the insurers and not the insured. I was also told I need to contact AA to resolve this and I feel it is the duty of the insurer to resolve the issue of towing charges with the service providers and not involve insureds. Costs were incurred for the towing of the vehicle and the insurer covering the event should pay the costs irrespective of who the preferred service provider is and any contractual issues arising from the situation should be resolved by the insurers, I am also deeply concerned by the policy administrators reluctance to provide me with the details of the client service and Claims Manager who have the authority to deal with these issues at policy and principle level as opposed to clerks who dont have the authority to override incorrect decisions by the junior staff. Secondly, my car is accumulating storage fees and I cant release it until this impasse is solved whilst people with authorities are not getting involved to remedy the situation. Its very cool for insurers to debit my account every months but when there is a claim, they drag their feet and do not want to take responsibility. This is poor service and should be condemned.
