Nokia — repair center damaged my screen. and refused a to take responsibility for the same

Address:

andheri west near andheri station.

I gave my phone to the nokia repair center "cell care point" in andheri west near andheri station. The problem was in the charging port as it was not charging. When they chacked they say my phone is damaged by liquid and 1800 will be the cost for that. I refused and said i will repair it later on because i knew there was no liquid damage on that phone. When they assembled my phone and gave me back the display and touch was not working properly i reported the same they is said it is because of liquid damage. I took a copy of the worksheet and came home when i plugged it to the charger it i charging and they have mentioned that my phone was liquid damage and that is why my display and touch is not working properly. And on the job sheet they have mentioned that phone has liquid damage and if its damaged by liquid then how charging is working.
