Edgars *****

I am an account holder at Edgars and i reside in Polokwane, on the 13th of July i received a message saying i must confirm if i made a purchase of +7000 in Durban. To my surprise they never send messages of purchase confirmations before and if they detected ***** why didn't the stop the transaction from going through that time. What security questions did the cashier ask to make sure that the purchase is made by the account-holder because i never bought clothes for that amount ever since i started using that account, 10 years back. I am ****ed off, when i called they asked me if i know what ***** is.
