I've had the opposite experience. OVH charged my creditcard twice for the same payment, then simply refused to see the issue. I sent screenshots showing both payments, they just kept reiterating there was only one invoice (which was exactly the point). And every interaction typically took about five days -- for each follow-up to the same ticket. Had to revert one with my creditcard provider.
With Hetzner on the other hand I've had technical support issues responded to adequately within two hours, multiple times. As a small individual customer no less.
