It seems technician is not professional. After making drilling he was not able to fix nail then I have suggested to put small wooden piece and provided as well and also he was asking another nails apart from provide by AO smith box. After completion of installation he should clean the things but he left uncleaned and then I have cleaned everything. His name was Amol Patil. After installation I received sms about the name of the technician. Ideally sms with technician name should get before installation so that customer should know who is coming to our home. Then I received call from Sachin Patil and asking happy code but I said Amol was a technician then why I can share with you so he said something app issues but this should not happened. I thought AO smith service will be good in Pune but it’s not like that even product is good. I will give same feedback in Google reviews as well. Thanks
