They don't know how to treat people

I was sooo disrespected, I bought things for R1200 and forgot to put away some jacket I didn't wanted to buy, got to the gate and it beeped which I wasn't aware. I asked to pay for it the manager didn't allow me to pay nor let me go, he said I stole which didn't make sense, and I am currently in trouble with the law. I have a credit with them and spent sooo much on the shop. from today I will never in my life buy from there, I hate it, Woolworths have lost the most valuable customer ever. they have no good customer service at all
