Rude agents and continued spamming

Just received a call from the rudest possible call centre agent. Calls me as a courtesy call to tell.me stores are now open for shopping. I said thank you and then he starts asking about my payment for the month. I told him I hadn't paid it yet but that I don't have time for this call now because he didn't bother asking if I am busy or not. I know for a fact he could hear my screaming baby over the phone but after I told him I don't have time for this call, he says "wow" and hangs up. If Edgar's wishes to associate with people such as these, perhaps I should just close my account.

All this is over and above the 7 sms's I received throughout the month telling me to pay my installment to this bank account or that bank account and then suddenly I should pay it at Checkers and then if I pay it at Checkers I van get a R200 voucher..... Does Edgar's not care about the MASSIVE inconvenience they are causing their clients???
