Is this billing dispute even worth my time?

Hetzner charged me twice for June. Identical line items, same invoice date, both processed. I opened one ticket. They responded with a form asking for:

• Screenshot of both charges
• Last four digits of payment method
• Declaration that I authorized neither duplicate

I provided this. They replied with a different form. This has now happened fourteen times over three weeks. The amount is eight euros.

I am invoking my right to a clear billing process under EU consumer protection frameworks. But I have spent approximately four hours on this. The hourly rate is approaching negative value.

Is the principle worth pursuing, or am I falling into a deliberate exhaustion strategy? I would appreciate honest assessment from those who have faced similar provider behavior.

Hetzner very bad already I hear that from friend too
They do this hos charge double many time
You keep ticket open they will tire first
Eight euro is small but your time also small
If you give up they win
I think fight for principle is good
You have right to correct bill

Why do they need 14 tickets for $8
Is this normal for hosting
I just got my first vps from InterServer and now im worried
