Cannot verify payment online or at branch

Dear Sir / Madam<br> <br> A tenant promised to pay me yesterday (18 days late), or else vacate the premises. He emailed a proof of payment from FNB. I tried to verify this on the internet, which is very complicated and fickle, meaning I do not know if I am entering something incorrectly on the internet, or if the supposed proof of payment is **********. I then visited the Hillcrest Pretoria branch. Although very helpful, all they could tell me was it looks legitimate, but cannot say for sure.<br> <br> 1. For me this is unacceptable, there must be a method that can definitely tell me whether the data is legitimate just from the traceID (5HJS4SVC) - airlines use a 6 digit number to issue tickets to customers, you have an 8 digit number. <br> 2. Can someone please tell me if this transaction (5HJS4SVC) and the following WGX4ZSVC are legitimate or **********.<br> <br> Thank you<br> Grantley Sherwood<br>
