Scam promotions. Awful support chat.
I followed a signup link on another app which contained a 30 euro promotion. After opening the account no mention of the promotion. I contacted the chat support which told me I was ineligible because a different promotion applied. Mind you this is after uploading personal ID documents.

The support representative could only answer with canned responses and links. (I guess in true German customer service fashion).

I've asked for my data that they've collected before closing my account, as per Gdpr. They can only tell me the request is escalated, no time frames. They claimed is due to having too much load due to the pandemic (1.5 years after it started).

How can you trust an organisation like this with your data, let alone your money?
