Jeeves And Flipkart - Warranty claim not fulfilled

My washing machine has been showing Error E* since **th January ****. I raised a warranty service complaint, and a technician visited my home on Monday, **th January.

During the visit, the technician performed some basic cleaning using a toothbrush. Unfortunately, power went off while he was checking the machine. Despite this, he charged ₹*,***, assuring me that the issue was resolved and asked me to try once power resumed.Trusting his words, I shared the happy code with him.

After power was restored, I tried running the washing machine, but the same Error E* persisted. I attempted to contact the technician multiple times on his personal number, but he did not respond.
I raised another complaint on **th January, but the same technician was assigned again. Shockingly, he closed the ticket without visiting my home. I raised yet another complaint on **nd January, specifically requesting a new technician. However, even this technician closed the case without visiting the location.
I am extremely frustrated and disappointed with the service experience. This has caused significant inconvenience, and the behavior of the assigned technicians appears highly unprofessional. Charging money without resolving the issue and closing tickets without inspection is unacceptable.

I request immediate intervention, assignment of a competent technician, and a refund of the ₹*,*** charged, as the issue remains unresolved.
Please treat this matter as urgent.

How can u mark the service done without even sharing the happy code!!????
