pdfguru – subscription trap – I got my money back

I used pdfguru a couple of times for getting “image PDFs” OCR-ed. Nice service actually. Cost me € 0.99 per week. Sort of really, really cheap.

But then they charged me € 49.99, and I found out, they thought, I opted for a monthly ongoing subscription. That’s called subscription trap, in German: “Abofalle”. I searched the web.

https://www.scam-detector.com/validator/pdfguru-com-review/ – go to the bottom of that page!

That’s mean!

I contacted my bank. OMG, what a painful process altogether!

I also contacted pdfguru, and asked them to reimburse me. They replied, that’s impossible. Once charged, they cannot reimburse me.

My bank accepted the “plea” and started the process. Several days later, pdfguru sent me a mail saying, I got reimbursed, A few days later the transfer showed up my cash account. I am happy.

BTW: If you are looking for a similar (but …) service, look for “pdf24” and then for OCR. I keep using their web page for that service.

GitLab: migrating from git_data_dirs

https://docs.gitlab.com/omnibus/settings/configuration/

They suggest, you move your storage configuration from git_data_dirs to gitaly[‘configuration’].

You should actually consider, whether you already use an assignment to gitaly[‘configuration’]. Otherwise your second assignment simply overwrites your first assignment, and you won’t see your repositories any more.
