Rude Cold Call Salespeople

Whoever you have making cold calls on your behalf to give out free car insurance quotes, is doing a despicable job of representing your company. Besides the fact that I have never given my information to King Price nor given permission for any communication from them, it seems King Price have bought my details and phoned multiple times to offer free car insurance quotes. When I explained politely that I already have insurance, the woman on the line became quite aggressive in her tone and said "but it is FREE and it will only take a MINUTE". I again mentioned I have only recently changed over to a new insurance and so I am not looking to change again, but before I could fully finish my sentence, she sighed and hung up on me. There is NO way that King Price could possibly consider that as proper etiquette. I certainly will not be recommending King Price to any of my clients going forward.
