Refusal to repay a deposit into the Luno bank account.

I deposited R 3000.00 into the Luno Crypto account but I was provided with the incorrect unique reference number. I had no idea I was given the incorrect ref number and used this number as my reference when depositing my money into their account for the purposes of trading in crypto currency. After about a week I had no response from Luno and queried what was happening to my money. I was advised to contact Luno support which I did, I was required to provide them with a bank generated PAYMENT NOTIFICATION which I did, I was contacted by no less than 5 different people who were responding to my query, they never once read my correspondence and sent me information about paying my money to a third party whch I hadn't, I was told that I was using another person's ref number which I was untrue I had no idea that the reference number provided tio me was incorrect. When I asked them to check my initial registration information, they ignored that and eventually I was given my correct reference number. I asked no less than 3 times for the new Ref number to be confirmed by Luno to substantiate it was correct, too date that has still not happened. I asked that my money, paid into their account with the incorrect Ref number, be repaid into my personal account, after providing my bank generated Payment Notification, which would show them exactly when the deposit was made, they told me to go to the police and report this incident, I am dumfounded at the incompetence. They are simply too lazy to trace my deposit and repay my money, it is completely unacceptable, seeing I have provide all the information requested for repayment listed on their website. How is it possible that LUNO can be so *********** and to how many other people has this happened. I need this to be resolved please.
