Nobody has ever been congratulated like this before.

Or, more likely: Nobody's ever been congratulated like this before.

Hi Illia,

I personally use "nobody has ever been congratulated like this before". The difference between the two is tricky, and I would personally use the construction with "was" if I were referring to a specific moment of congratulations in the past where the congratulation given was not very common up until that point. For instance, "when the allies returned from WWII, they were given medals of honor and were regarded as heroes by the public and by their family for the rest of their life. Nobody was ever congratulated like this before." This implies that before that time in the past, people generally weren't congratulated like that. This is how I make sense of these two different sentences and I hope my example makes sense.

In conclusion: I would use the "have" construction.
