Pyjamas

I bought pyjamas @ jumbo store when I reach home I notice that I took XL instead of XXL and when I return it I was told I can't return it I must read the till slip, if I was told prior payment I would have not taken the pyjamas.

I even left the pyjamas I was returning because I don't need them, it's worse the correct size I'm looking for its there.

The manager gave bad attitude , I'm not happy at all
