i want to block an account

Hi,<br> <br> I'm getting married on the 21st of May 2016 and was looking for a Photo booth company toe come take photos at my wedding. So I got in touch with The photo cornor. They sent me a quote and said i must pay 50% deposit to book the date. On the 9th of October 2015 i made my Deposit, now when i try to finalize the details with them for my wedding their phone number is not working and i see alot of people on their facebook page are complaining about them *****ing money. So i would please like for you to stop their account and please pay me back the R2150 deposit that they stole from me as it is alot of money for me especially for my wedding day . I tried contacting the ***** department but after 15min of waiting for a answer my phone died and i dont want to waste more money. Can you please help me get my money back and stop people from making the same mistake.
