Letter to broker that called me yesterday

Dear Mr Broker/Sales person for Forex company,

No, I did not download your trading platform recently. It has been several months since I have downloaded any new trading platforms onto my computer.

A little side note about the conversation: I received a phone call from a broker, I guess it's a normal follow up call, that didn't actually occur until several months after the fact .... As soon as I mentioned that I was trying a trading robot, the tone of the conversation changed.

First of all, it is rude of you to assume that my only experience with trading has just been with the trading robot that I had just purchased. I could have had years of trading experience, but no as soon as you heard I was using a trading robot, you were no longer interested in my business.

I have been a trader off and on for a few years. I know how to generate returns on the forex, options, and stock market. So mr. broker, you have lost a potential customer from ever doing business with you or your company.

Good day to you sir
