Edgars Account

I had fully settled my edgars account and in October on the 12 made a purchase using an account at Egdars store in wonderpark for R249. 00 and and that same amount being the outstanding balance on the account at the time and no further purchases. I had gone to the store everytime their system is offline for payments. On Saturday I received a call stating the balance due on my account is R800. To my surprise I had only bought for R249. 00.
