[Resolved]  Urban Company — Service/installation of AC

While installing and servicing the split AC by Urban company we noticed to he flap of the AC was not evenly closed from one end.We raised the issue with the professional, he tried to fix the same by twisting flap and lock of the flap so that it can be adjusted.After trying for 20 min he wasn't able to fix it so he placed all blame on us saying the same was earlier like this only.we also raised the issue with the Urban company but senior professional were also not able to fix it.They cant fix it because the professional somehow has damaged the particular part while installation or servicing.My problem is if the flap is not closed properly the dust will enter the AC more often even if it's not in use.This will decrease the life span of AC.Urban company is unable to provide any solution as they are saying it was not professionals fault.Please help with the same.
