Urban Company Mumbai - Product tampered lost warranty

I had a booking to repair fridge. Issue *as no cooling. This booking was made on *st Sep ****. Technician arrived and tampered compressor (which was under ** year warranty by Haier). Issue did not get resolved. Same technician came again and total Amount I spent was close to ****/-. Later the case was escalated to senior technician on *th Sep ****. During *nd week of Oct ****, issue started again.
I submitted revisit request, but I received a call stating they cannot assign new technician on my current booking and I should cancel the booking and make new booking to get technician.
During this time, i was said that the amount will be refunded and I specifically mentioned them it's not about refund but I want the issue to be resolved.
The ticket was marked as complete, refund was initiated amounting to ****/-. During this communication, I wasn't informed that this will hve me loose my warranty for the booking with Urban Company.
I did new booking and the technician came and told me he is not asked to do any job and he left. The same booking was cancelled by Urban company and refunded money that I paid amounting to ***/-.
I called technician from Haier and was informed that the compressor is tampered and warranty is void.
Urban Company is liable to pay the damage and agony caused.
They have been denying to look into the case referring they have refunded the amount and company is not liable now.
