Lava Mobiles — cheating by service centre at srinagar kashmir

Address:

Srinagar, Jammu and Kashmir, 190002

I replaced a battery of my lava a76 plus at unique mobile care at srinagar. They charged me inr 600 for the same and didn't give any receipts for the same.
Later i received a message from lava care as a receipt of my order and found it very different from the work order.
I was given only a battery for a76 plus
And charged for adaptor and usb cable too which i never received.
I request to take necessary action against the said lava care centre and return my undue amount for which i was cheated by your pos / centre.

I hope i will not have to strive more to get the said lava care centre corrected

Thanks
