Is the owner of the flat responsible for pipe damage / clogging?

[Differ Daneho]

I am renting a flat and I have a problem with the owner of this flat. The outflow of water from the bathtub was blocked completely suddenly. The landlord is now on vacation in a different state and sent me a message that I should use an old hanger to get my hair out of the tub. The pipe is clogged somewhere deeper. What can I do now, but most of all who is responsible for the repair - me or the owner of the apartment.

Please give me some suggestions.
