Coca cola and my coke rewards are scams. They make it difficult to earn rewards by making a smaller and smaller limit of how many points can be earned within a week. Used to be 120, now it's 75. They recently created another hurdle, earning "status". This must be earned as well in order to receive any reward from their site. To "earn" status you must do free advertising on behalf of coca cola. You are required to post commercials and ads to twitter. But once you do, you will still not earn status. They felt they didn't have enough money so they created the scam my coke rewards to make you think you can earn rewards when you buy their garbage.
By making it harder and in reality impossible to get anywhere with their rewards site they don't have to spend a dime on new rewards and get to collect a fat check from each of their "sponsors" in whom they make you advertise on twitter. This company is pure evil. Don't bother contacting them. They don't respond to complaints, they are confident they will have enough in profits to keep up the cash flow no matter what they do. My coke rewards is a bait and switch scam plain and simple. You buy their product, do free advertising for them, put in codes and you get nowhere. They get rich and you waste time and money on their scam. File a complaint with the FTC at https://www.ftccomplaintassistant.gov/#&panel1-1 and put a stop to this.
