DEDUCT MONEY IMMEDATELY BUT NEED TO SHOW A POP- IS NOT EVEN DONE BY EFT?????

The product is only online available and when it is paid immediately not eveny by card or eft you need to send proof of payment of pop? Is this a way of keeping money and take time for delivery. This is totally rediculous it is deducted immediately from your bank account so why will it not shows? If it was a EFT you can understand that....but no it is not!
