[Resolved]  Siemens Home India — dishwasher not cleaning properly and complaint raised before a month. still not serviced but my complaint got closed today stating it is serviced

I registered a complaint for servicing my dishwasher on sep 29 with siemens customer service. I got reply that within 72 hours an engineer will contact me.
Its been more than a month and so far nobody turned up.
I contacted customer service every week and i got the same reply. The customer service representative will apologise for inconvenience and confirm that again i will need to wait for anither 72 hours and someone will reach me.
This happened for 4 weeks. Everytime when i ask the customer service representative to escalate he will provide same reply as an engineer will contact in 72 hours. I am really surprised how a corporate like siemens doesnt train their customer representatvies regarding the escalation process.
Today to my shock i discovered that my complaint has been closed stating engineeer visited and completed service. But nobody contacted me. When i called the customer service for help, i got a reply stating that my complaint has been closed and i will need to raise a new complaint and wait for another 72 hours.
When i asked him why my complaint was closed without informing me and what action is going to be taken on the service engineer who closed the complaint without servicing, he replied that he can only register complaints and the service department closes it. He cant do anything about it.
If that is the case what is the need for a customer service representative, an automatic machine can do this task isnt it.

I am very disappointed and frustrated at the way a customer is being treated. When i asked for process to escalate the complaint, the customer service representative put me on hold for sometime, came back and replied that he checked with seniors and there is no process for any escalation and i cant do anything about it.

Till now my dishwasher is not serviced.in spite of me following up for a month i was simply pushed off saying there is nothing i can do about it.
