Exact - Poor customer service

I went to Axact store Limpopo Mall today to do exchange of clothing that were bought at Axact store Gauteng by baby daddy were send to Polokwane without a receipt by the sender. The size were small and when I went to Axact Limpopo they are saying I cannot change them without the receipt, I can only do exchange without a receipt at the store the clothes were bought from, like seriously. And they telling me this after waiting 20 minutes or more since there is no one at the entrance telling us what is needed to make an exchange and that they only have one person who do exchange and she's at the bathroom at that time. I'm not happy at all with the service now I have the child clothes and I have to wait I don't know when to send them back to Gauteng.
