Bad customer service with *******ion

Hi

I bought a meal in Chicken Licken gateway and I wasn’t served for 30 minutes then I went to ask for my refund. They did something with my card and gave me a slip. From the 22 of December till today there’s no refund and when I call it not going through and one lady did answer and she told me that someone is going to call me back until today there’s no phone call
