Bad attitude from Staff

I read that Woolworth does offer 3 months layby with 30% deposit. I went to Woolworths in Johannesburg CBD to do layby for my kids so I took the clothes to the till and I was told by the cashier that they don't do layby but I insisted that It is allowed,I wasn't allowed to do that. I was ****ed off cause they had the clothes I was looking for. Tell me Woolworths in Johannesburg CBD don't you do laybys? I realy need to know.
