ABSOLUTE nightmare!!! Withholding customers funds!

PayFast has still not allocated funds paid via Instant EFT , 5 days ago! My order has now been cancelled with Takealot due to this. PayFast refuses to deal with me directly, the person whose money is sitting in their account. PayFast has also given no feedback to Takealot! What exactly is PayFast doing!? Keeping the funds from how many people in their account in order to gain interest from their bank?! There's no other reason for PayFast to be withholding funds from Takealot for my order! I am furious! I will NEVER use PayFast as a payment method again!
