Beware: Webuycars hold onto your R5k holding deposit

Webuycars happily take R5000 from you to reserve the option for a few days to purchase a vehicle and they take a week and 3 days just to tell you they can't pay you back because they need a document with the proof of bank account to make the payment (despite numerous calls and messages). They do have my banking details because I purchased the vehicle from them and submitted all financial information needed to pay off a vehicle with 1/3rd of a million Rand??? Be careful of this one way street where they hold onto your money.
