Facilitating Phishery?

I received two SMSes this morning at 09:34. The first reads: "Kindly note that your account SNG6266 with Mr A. Singh was emailed to you today. Please arrange payment of R109.29 within 30 days. Ina. Tel:***"

The second reads: "Banking details for Mr SINGH: BANK: FNB, BRANCH CODE:204809, ACCOUNT NUMBER: ***1, AMOUNT: R109.29. Please use ***"

Since (1) nothing was e-mailed to me as claimed, (2) there is no description of how I came to owe Mr A. Singh R109.29, (3) the amount is quite small, (4) I don't know Mr A. Singh from a bar of soap, and (5) I have no idea how this claim arose, I am forced to conclude that it's a phishing con.

Consequently, I request that FNB investigate this account in order to establish its legitimacy or otherwise.
