(Anecdotal evidence) While I've been happy with OVH over the last year, literally last night they suspended my servers because they weren't able to charge my card.

No warning that they would charge it, no pre-authorization, no grace period to rectify the problem, just shut down the servers at 2AM in the night.

Not happy to say the least.

Curious, how long have you been running your service with them? A few months?.. years?

This was the first year I've been with them, and pre-paid for a year of dedicated servers.
