Haier India Deep Freezer — Service request closed without my knowledge, Rude behaviour

My Haier Air conditioner is not working. I had raised service request on 5th June 2023. I got a call from Haier service center (Puri, odisha) and assured to do the service within 24 hrs. But they kept delaying it and eventually stopped answering my calls. They cancelled service request without my knowledge.
I raised another service request on 8th June. They again cancelled it without my knowledge.
