Dear Sir /Maam my i-ball mobile handset with broken touch screen had been given to “best IT world (India)Pvt ltd, Dibrugarh” for replacement of the touch screen on dated :13th November 2015, but yet have not received it. Whenever I call to the concerned service center they postpone the delivery date with some sort of problems. The document no against the repairing work is : 137021561971515. Thanking you Mithu Chetia
