Row matrix not being enabled

Please don't judge my way of circuitry, I know I could have created net but the bigger problem lies in the function. I am creating a 8 x 12 led matrix. I didnt have another uln2803 so I used 4 bc547. but the problem is, no matter how much code I change or test code I write, I cannot enable row only. Entire column lights up, If I want to glow the top left led, entire first column lights up. what can be the possible solution for this?
