Realme - Compromised camera and screen after servicing

On **/*/** i went to techplus service solutions, Davangere, for the replacement of my phone's screen , they gave it the on that in evening , which in night turned black again , i went on the **/*/** again and asked for another replacement , i got my phone that day only but with compromised finger print sensor and blurry visioned front camera . When i went to them again , the staff was very rude and their engineer was not accepting the fact that they did something wrong , later on **/*/** i searched for other realme service centre and went there. Where i got to know that techplus service solutions is closed now . The later one also told me that the screen they put in my phone is not original and my front camera has many scratches over it .
