Sad, disappointing and embarrassing service received

Disappointing and embarrassing service received from Cornubia Truworths.

I normal order online as i don't have time to go out. I ordered a few items. 1 item was not suitable, was a lunch bag. I had the tags on and i printed the receipt. It has been 1.5 months i had it and supposed to return it. I went in not expecting a refund but maybe a gift card so i can buy online or if i do come back then can use at a later stage. I was told by the cashier to chose something and thy can exchange it. I agreed as i understand i took long to return it. So i went found something in the store , it was more so i siad i would pay the difference. I ended up going to another fashier by the name Tina. She said the item needs to be refunded in my credit card then purchase the new item. I said ok, but i couldnt remember my pin as i have never used my credit card instore ever, online doesnt require a pin. So the cashier seemed annoyed. She was talking to her collegue next to her and complainig. The manager, think that what she is, her name was Nadine. She said they will just do an exchange. I said that is what i wanted initially. Mind you the branch was busy and everyone was looking at me. So i said which card should i pay with. Nadine said anycard. But Tina said it has to b the credit card. So im standing there embarrassed as thy made me feel like i came there begging for something. I just told them if they cant do it just give me the bag back and i will leave. They talking amongst themselves and said they doing it. The level of service has seem to b lower than i expected to be from such a renowned franchise..Why does it happen, that the one time you have the chance to go out, and it just gets spoilt by someone who feels they know everything. 😔
