capitecs client got my money and didnt send me

I purchased items from a capitec client on olx i sent an immediate eft payment and the seller told me the money was in his account. That same day when my courier arrives at his place he wont let the goods go, now saying the money has not cleared his account!!! I paid an extra sum of money in order for the money to be in his account with immediate effect, he has now been reported to olx and they have suspended him from advertising on that site. This matter has also been reported to absa and to the police. I have told this person i want my money back but as yet nothing - i would advise you to get your client to refund me immediatly before this matter is taken further he has ****** R2500 from me.
