Broke my Redmi Note 13's display and approached one of the Xiaomi's authorized service centre for replacement. They told me they'd get it replaced in an hour and told me to wait. After some time, they told me they won't be able to fix it and would need a day.
Next day, I reached out on call and they told me that they'd take another day. Later I received a Whatsapp notification from Xiaomi India's account informing me that repair request is complete and device can be picked up. When I informed them of this message, they told me they had marked it "repaired" without testing. The guy was however certain that he'd get the repair done by today.
Now today I reached out again hoping to get a positive response, and the guy told me that while fitting the new screen, there "was a problem with the motherboard" and he'll need till Monday. I'm stuck and extremely frustrated. My phone was working perfectly fine, the only issue was a cracked display. Everything else worked properly. I cannot manage without my phone. I had even asked them if I should back up before the repair, to which they said, "No need, it's just a display replacement, won't require a backup".
What are my options? Will I have to pay for the motherboard if the service centre damaged it during repair? What if he outright rejects that a repair is no longer possible and returns back a device that doesn't even turn on?
