Xiaomi India — xiaomi mi a1 display price

Mera mia1 phone ka display ka sirf glass gir ke toot gaya tha then i contact to service center of jaipur to replace display
They said... 3800 rupe charge hoga combo change ki jayegi
But muje lagta h unhone sirf glass change kia hai phon ka dispay nhi
Or chanrge pura lia hai
Phone warranty me tha par bill pe likha hua hai out of warranty
Mere pas us service center ka bill hai jo attach kar rah hu
Plz consider it...
