Why did you stop sending statements?

For quite a number of years I have done my shopping for clothing at Edgars. I would buy on account and pay it off over the interest-free six months. During January 2015, I received the last statement from Edgars, which like always, I pay promptly. I did not keep track of the amount owed, but just like any normal person would deduct: because I didn't receive any more statements after that, I didn't owe any more money on my account. Four months passed and I didn't receive any correspondence regarding an outstanding balance, until today. Today I received a letter stating that I have an amount due of R634,20 and a balance to the account of R837,86. Yes, that is more than R200 interest, which is totally unnecessary and due to Edgars's Accounts Department being *********** in sending statements.<br> <br> Edgars might argue that it is my responsibility to pay even without them notifying me, but in any fair practice it is the seller's responsibility to send the debtors monthly statements and also notifying them of interest added to their accounts.
