Voltas AC service center , Raigarh, C.G.

Hi, My AC was stop working and than I registered a complaint in VOLTAS customer care before 6 days. They said service man will come within 24 hours and your AC will be reworking in 24 hours. Than next day I got call from local service center. Than after 2-3 call they sent their service man. That also was not able to repair the AC. Than he went back. Than again I tried to call them so many times than after 2 days they came again and took some parts from inside my ac. And now it’s been more than 6 days they are not even receiving my call, and the customer care saying next day – next day. So both customer service and service center of Raigarh , C.G. are harassing regarding the service to repair my VOLTAS ac and no action are been taken by the company on them.
Still waiting to be repaired my AC.
