I complain once. Then I walk.
Same way with food and airline.
If I feel justified that I am right - and I still feel wronged ... I walk.
With the response from customer service being absolutely legal within their rules ... but absolutely anti keep-the-customer in their response ...
I'll walk. I'm plat with Marriott and have generally been treated very well ... even when I've been wrong
I have the Choice Visa ... now, what do I do with that!
