Vijay Sales — ac commissioning

I have purchased a Window AC Hitachi RAW318KUD on 19 Apr 2019 and the same has been installed on 23 Apr 2019. The Service Engineer who visited on the same day for commissioning of the AC did not have a multi meter or voltmeter and could not carry out the necessary commissioning checks as mentioned in the Owner's Manual. He stated that another Service Engineer would visit the next day. Till date no Service Engineer has visited for Commissioning of the AC inspite of repeated requests on Vijay Sales customer care no[protected].
