On my June cking account statement, I noticed an unidentifiable/unauthorized charge of $11 posted on 5/27.
I don't recognize this company, yet my credit union told me it was a point-of-sale transaction (i.e., we used a PIN to authorize the charge). I contend that it was unauthorized; I don't know who this merchant is.
Immediately record every transaction made w/your debit card...every transaction...and check your account online at least twice a week.
