I was expecting a money transfer from Australia via Western Union Bank

I was expecting a money transfer from Australia via Western Union Bank. I received a call from Sikhona Money Transfers requesting me to fill out a questionnaire in order for them to place the funds into my bank account. I immediately thought this is a ****. I know nothing about these guys, no one told me about this. Anyway, after visiting a Western Union branch (at an Absa Bank) the staff also knew nothing about Sikhona Money Transfers. They did supply me with the International Banking contact number which I called when I returned home. They confirmed that the company was indeed legit and I proceeded with filling out the information by following the link they sent me. I immediately received a confirmation email thanking me for using their services. Well, 20 minutes later I received another email confirming that the funds are now in my bank account. When I checked my banking App, the money was there. Really great service, thanks!
