Unnecessary calls

Yesterday I was doing a "quote" online and it kept giving me an error, now surprisingly someone called me back and advised that they received a request from me to call back regarding an Insurance quote, I advised him that I was actually doing the quote online and didn't want to take a call as I wanted a quite for quite a few assets, we then agreed that he can call me anytime today, surprisingly, I've already been called by numerous people wanting to do a quote with me and I told them that I've made an appointment with someone already, the other guy kept insisting and I refused. To cut the story short, please don't call me anymore, kindly remove my numbers!!
