HTC — Htc service center broke my sim slot

Address:

Mumbai City, Maharashtra, 400053

Hello sir I had given my phone in service center becuz I had wifi signal problems.I gave my phone on Monday they said it will be repaired in 5 days I said fine on the 5th day when I dint get any call I called them they said I have to pay 6000 rs I asked why they said my sim slot is broken my speakers are not working and my motherboard has some issues.I asked him how is it possible he started giving some excuses.I told them leave I don't want to pay 6000 give me phone back my phone is also in warranty got it 6 months back.they returned my phone unrepaired but as I got my phone my sim slot was broken my motherboard and all other things were working fine.I submitted my phone in prime mall irla they are bunch of liars and scammers cheating people.And the big joke is after giving back my phone unrepaired they are still asking for 550 rs I refused to give them now they are threatening me that my phone will be locked by Microsoft I am not stupid to believe this crap please look into this matter.Never buying an htc phone again.
