I went to see my broker for insurance. I gave him all the necessary information. I was given a quote but when I received the papers from the insurance company, the amount was higher. Are they allowed to do that?
Unfortunately, yes they are allowed.
After being provided a quote by your broker, he then sends all the documents to the insurance company. The quote you receive from your broker is the total estimated policy premium but it needs to be approved by the insurance company.
Therefore, if the broker made a mistake and the amount is higher than what he told you, you have the choice to pay the amount charged by the insurance company or shop elsewhere but you cannot force the broker nor the insurance company to honor the initial quote received.
