Xiaomi India — MI robot

Address:

Chirayil, Opp muttom church, cherthala

I raised a complaint regarding my robot on September 1st. Have been contacting the toll free number daily. I was told consistently that a technician would attend to the complaint. On 3rd I was given a token number M 2098314. Every day I was assured that somebody would attend to the robot on 4 th I received a confirmation SMS that somebody would visit at 13 PM.
Nobody came. Subsequently I was told that a service part is needed and that it would take 10 days. Since nobody visited my house., I'm unable to understand this procedure.
Today i contacted the number. I spoke to the person attending the call and she said she'd put me on line with her supervisor. But a similar ranking person spoke to me and after some time she told me that she was connecting me to her supervisor. Though I stayed online for 26 minutes, nobody attended. I contacted the number again and was told that since the information updated was that an investigation into my complaint has been made, no action could be taken till 14 of this month. I would like to know what relationship the investigation has to the problem in my robot. I would also request that action be taken to rectify it
