Money hostage

Horrible service I had to use them for a ******** check for my pdp a accidentally paid R1000 more than I was supposed to I got in contact explained my situation and sent them proof of payment bank statement and copy of id they informed me that it will take 2 weeks to process can’t see why so long but okay it’s now been a month. I get told last week no it will be processed of Friday then I get a email this week sorry they did not do it and hopefully have time to do it this week my money is been hold ransom technically as it’s been over a month and I’m having no joy I’ve called them I’ve left messages for manager to contact me I’ve asked to be put through to a manger phones just ring any how I’ve been driven to post my story here and will see if they have a face book page if I have not herd from them and my issue has not been resolved by the end of this week I will be forced to lay charge of theft as my money was not returned to me there communication is **** horrible company
