I don't understand. Are you trying to advertise that you run a company. Or that you pay 30k to witribe (which is cause for concern) or simply want to call them out but want to warn them first (in which case a formal email works). I really do not get why you posted what you did. Also just a reminder: you are a consumer. Do make your choices. I'm fairly sure this won't work out the way you think it will.
Cheers.
