Very bad service, Samsung steeling my money and phone.

On the 3rd of November 2022 I handed in my phone to get the screen fixed, I went to the shop multiple times after they were supposed to give me a quote, each time I had to wait for the person working with the phones to contact the repair shop, each time she told me she would send me an sms, only on 13 January I received a quote. I had to pay upfront and I did. She told me at the most it would take 7 days to receive my phone back from the repair shop after paying the amount. I am still waiting, after 2 weeks, and no phone. Today I told them to give my broken phone back and the amount I payed. I was told they would give me a call to arrange the banking details before the end of the day, I am still waiting. And still no phone
