If you happen to be in the EU or if you qualify somehow, you could try submitting a GDPR request for all your data, which they are legally forced to respond or face steep fines.
As I am from the EU and both a business user as well as an individual customer with the same issue I did exactly that. They ignored me flat out multiple times. It was very rude. I got it on record though so we'll see how legal goes about it. Doesn't help me get to my data any faster though. ;-/
