If the auto insurance is about to expire, I suggest you apply for renewal this year through last year's salesman, so that the salesman can help you do a lot of things, especially after you get out of danger, and it will help you deal with a lot of troublesome things. The cost is the same as going to the company, but it will save you some links, such as filling out the insurance application form (of course, I need to sign the insurance application form) and copying materials. Telemarketing is a way of direct sales from the headquarters of insurance companies that has emerged in recent two years. If you want to save money, you can buy auto insurance by telephone sales, but you can only deal with the insurance company yourself when providing follow-up services. It is suggested to handle it through the salesman last year for reference only.
