Lufthansa — water dripping from the overhead ac duct : bad service

Address:

560061

On 10.12.2017, travelled from bangalore to frankfurt (Lh755) seated in widow seat. Before take off, all of a sudden, water started pouring in from the overhead ac duct on me and got fully drenched and started shivering (Cold water) due to condensation. When i complained about it to the crew, they said that it is normal and i need bear with this situation for some time. When i further asked for help, they provided some tissue paper and informed me to wipe it. Further, water drops continued and no support came from the crew staff and they did not even bother to check whether i need change of seat or need some more tissue paper to wipe. It was not a good experience.
Looking for feedback on maintenance of aircraft air conditioning system in lh flights.
