Edgars accounts handked by RCS shoking information

I have had conducted an Edgar's account for the past 40 years on a 6 months interest free basis. Now that the Edgars accounts are handled by RCS I get charged an interest rate of 24 per cent plus on my small outstanding balance.I would like to point out to all Edgar's customers that it would be better to pay by credit card and purchase your goods at other stores where you can get rewarded plus you can get rewards on your credit card when using it.
