VPS not paid at time, even paid after no service neither data

Hello,
I count quitting OVH, I want to know before if someone have got that and what to do in my situation if you can help please.

I am using a host name and vps with ovh in order to use for personal usage. I have got the vps billing for year service not paid for about 2 months. I paid after two months and got no service even if paid. I lost my data, but this is not a problem as I use the vps not too much for some development.

Have someone got this and what have you done/got from ovh ?

Thanks in advance
