Reliance Trend — t shirt price charged three times in bill

Some days back I went reliance trend in park squ are mall banglore . I did shopping of around 6k but when I checked bill at home I was shocked to see they charged for a t shirt 3 times in bill . I called to store also but they don't want to listen. I went to store with my husband but first we have to waitt for 1 hour then they said manager is not there so we have to come again. I complained it before also they called me listen my complaint but not my issue is still unsolved. I didnt get my money back. I am attaching the copy of bill and hope I vl get my money back. II suggest others not to shop from reliance trend.
