Thought I will just inform you guys. Be wary of EFT proof of payments. I got one last week that is virtually the same as the real thing. The give away was that my bank statement shows a cheque deposit, whereas the proof is for a once off eft transfer. That and a poor story of why the money was wrongfully paid into my account and why I must pay the money back immediately.
The marvel is the copy of his receipt. I could not tell it is fake and on presenting it to the bank, they pointed out a few things like font etc. But to me it was the real thing. So, a faxed copy of a payment to your bank account can no longer serve as definite proof.
