Santander online Services broken for months

This is an issue with the German branch of Santander.

The only way to reach support is either via phone call or contact form with a strict character limit and no ability to send urls or images.

Multiple times, since months now, I have messaged the Santander support about the fact that during the purchasing process of a new credit card (Best Card Smart) the link to the terms and conditions is completely broken and the pdf document does not exist. It can not be downloaded. (Only happens if you select that you are a student: vertragscenter.santander.de/api/terms-and-conditions/BEST_CARD_SMART_STUDENT

I have made this issue known multiple times now, but I have been ignored. One person from support even claimed, that the product does not even exist. Well, obviously it does. It is listed on the front page of the website. I am just one click away from buying it. But obviously I am not signing something which I am unable to read.

Overall the services of Santander have been a major let down. Creating a shared savings account has taken months, because we were required to appear in person and people at our local branch kept delaying the creation, even after weeks of waiting and multiple phone calls. Apparently they forgot or just didn't care.

Online banking is full of bugs and some features appear to be completely broken.

When initially creating my account with Santander, I had to use my mobile phone and restart the process multiple times, because on PC the entire website crashes and will not complete the sign up process at all and on mobile there were also many bugs, which required me to restart a couple of times. I have accounts with 4 different banks and none other has had any issues of this nature.

WHERE CAN I REPORT BUGS?

WHEN WILL SANTANDER CARE?

HOW CAN I REACH SOMEONE COMPETENT?

Santander is rebranding in Germany (to Openbank) and will most likely go all digital. How is this supposed to work, if even the simplest of online processes (buying credit card, creating account, bank transfer templates, mobile app account overview, etc.) are broken, there is barely any support and any concerns are being ignored?

Does anyone have similar experiences? Is it the same for other branches of Santander in other countries?
