Great Customer Service!!!
I am an individual (non-professional) coder. I have been using TwelveData for several years. One evening a couple of weeks ago the data from TwelveData suddenly was not downloading properly in my program. I emailed customer service and got a response back within 10 minutes. After a couple of emails back and forth they provided me with enough info that I was able to solve my bug. The service people were very knowledgeable and thorough and as I mentioned prompt. I really appreciated their efforts.
