[Resolved]  Hitachi — I'm complaining about service.

My registered number is not working.
Few days back i called hitachi and told them this thing so they changed the number.in their records they have even not entered my right address but the strange thing is ac came at right address and installation b oh y also came at right address but when i called for service thay are telling me that the address you are telling is not that same wow. Also he said what your installation is not done through hitachi service but i installed my ac only by contacting hitachi. That installation boy only gave me one number [protected] saying that if you face any problem then you can contact on this number. After some days of installation i found that water is leaking from compressor so i contacted the same number that installation boy gave me and hitachi employee only picked it up that time and i told the problem and their service boy came to fix it. See now also they have come to right address but in their records address which which was present was wrong how strange it is.
My ac warranty ended on 20.05.2020 which means in lockdown. So when lockdown opened i contacted hitachi customer service now what they are saying your ac is out of warranty you have pay for ac service. From two service i haven't got any one. When last year summer came to end i contacted the same number given by i installation boy. So that time what hitachi employees were doing is everything time i call them and what they tell to me mam a message you will receive you can contact to that number. This happened many times. So after some days i just left calling thinking that.in next coming summer i will call for service but this time in summer it was lockdown going on. Is that my mistake that lockdown was going on. I want one service.
