Sh&t service at woolworths wonderboom junction

Disgusting service at woolworths in wonderboom junction. I went to exchange a pyjama and sleepers. The lady examined the pyjama for a very long time. It has not been worn yet and she confirmed that it was not worn. When i took in in quagga centre it was in a hanger of 13 years, but the size was for 11 year old. The lady says have stained the pyjama. It's invisible stains that were not notice even where I bought them. She's accusing me that I stained it. Calling people to come and see as well. I will never go there, it's the first sh&t service I ever received in any Woolworths. People like that will remain cashiers for the rest of their lives because there's no customer service. Shame. I will go somewhere and buy a pyjama and definitely not woolworths.
