I probably just got annoyed with a bot

[Phentex]

I ordered something and was supposed to get 25% off. My confirmation said so. But I was charged full price instead. So I reached out through support and just could not make them understand that all I wanted was a refund of the difference paid. Instead they placed an order for a new one at the lower price and I can just return the first one for a refund if I want. Minus the shipping cost which by the way was free. But I have to pay shipping for the return in order to get the refund. I actually said to the bot make it make sense!

And then I realized what I have become talking to a bot. So I'll do the return and go on with my life.
