During servicing the swing motor got damaged by the service man..He assured me the part will be replaced free of cost by urban company.Next day...another technician came for changing the part..As my ac is brand new and Hitachi make, I asked him to install the original part and show me the bill as proof. BUT HE DENIED AND WENT AWAY SAYING TOMORROW HE WILL COME TO CHANGE THE PART...From that day till today, no one has called back, neither the customer care o[censored]rban company is responding.Please resilve this issue or else guide what next steps should I take.
