All they want is your money. Horrible customer service.

I got a biannual teeth cleaning and went in a mere 2 days early and got charged $200. I tried calling Delta and no one would pick up after hours on hold, so I tried emailing them.

After 2 months of no communication from Delta, I get an email saying my request was denied. I was off by just 2 days, while they took 2 months to reply to an email...how is that ok?
