Do you also give a crappy tip to your server when the food didn't taste good? Do you yell at the cleaning crew in a hotel because the hotel didn't let you do a late check out? Do you give a customer service rep who assisted you and answered all your questions a bad score because a sales rep gave you inaccurate information? Don't ruin another person's day just because you're having a bad day. People are just trying to do their job so they can pay their bills. If you are really not happy with the company just leave the company and take your negativity elsewhere. Or better yet, just save everyone the headache and don't purchase service with any company. Since you hate sales and marketing so much, that will show them!
