Bad service

I am not happy with the service at Exact Protea Glen, I was assisted by Kamo.....I went to exact a week ago to exchange and I didn't find my size...then went back again today for a refund so I can purchase at another TFG store, I asked for a refund but she says that the company does not allow refunding a customer using a gift card....I wanted to know how true is this....I am utterly disappointed
