Fridge freezer

[Kafri]

no idea if this is the right place to post but perhaps you someone could point me in the right direct if it's not...

I managed to pierce the back of my freezer earlier. It's a small hole and I certainly can't hear any gas escaping. I've just checked the food in there (2/2.5 hours later) and all food is still frozen.

Have I done any damage or may I have got away with it?

Is everything still frozen? I'd get a tube of white silicone and fill the hole.

All appears well at the moment and it's been nearly 24 hours. All food is still frozen and rock solid so FC!
