How to fix dents on metal fridge door?

[Hayaimi]

I would like to know how can I fix all these dents on my metal fridge door on my rented premises without disassembling the fridge itself?

My only suggestion would have been to use a powerful magnet to pull the dent out. But after trolling through some you tube videos it dosnt look like an idea that will work to well.

The only other idea I have is to maybe use a combination of hot water poured over the dent area and straight away using a suction cup pull the dent out. (found this online but like the idea) The metal of the fridge is thin so you may be lucky.

Where can I find suctions that are strong enough and small enough to pull them back to normal?
