Urban Company — Technician messed up with my washing machine huge cost to repair

My washing machine was in working condition except water drainage problem on 26th October 2022 before your technician comes
He said there is problem in pcb he took my pcb with him and comes on Friday 28th October at 1 pm with repaired pcb and start reinstalling it after around 5.30 pm he told me that your door lock is also having problem so he makes another booking for door lock in URBAN CLAP app.
Then after few days he asks me to cancel booking.
Now my washing machine is in very bad condition and Siemens technician asking for Rs 20 thousands. I provide you the Siemens tech phone and screen shot already in chat.

I demand compensation for this.
