Some sort of ****

I really don't get this company's policy, I have an edgars account which I will cancel soon, I bought a cologne with my account which was round about R900 in July, I have paid R400 towards the account, I make sure I pay every month, but I checked my statement this month, and to be honest I was really perplexed to see that I still owe R911 can some explain where the money I paid went too? Like I really hate this brand right now. I will settle the full amount and cancel, I have my proof of the amount I have paid which is my receipt and I will ensure I spread the words so everyone sees how edgars *****s from people, to avoid other people falling in the same trap. Really shocking
