I am satisfied, except for the number of consultants one has to talk to , requiring same information,before getting to the actual person allocated to assist me. Another frustration is being asked for quote for car service, for a claim to be authorised. How is it possible that a technician may know how much it will cost , without first seeing the actual damage.
