Edgars must stop calling me for nonsense

I have an account with Edgars that I opened while I was still a student and had temp job after. A month before my contract ended I went into Legit in Mdantsane city to contact the customer service to try make arrangements as I was not going to afford my full installment going forward and trying not have my account get into arrears. The lady on the line told me I cannot make an arrangement as my account was not yet in arrears. My account is now in arrears as I cannot pay the full installment. I then contacted Edcon call center again to make arrangement, we agreed to a payment of R200 by the first on each month. I have now moved to a different area and there are no edcon stores around where I do my errands on the first of each month. I then make payments to my Edgars account via eft, understanding that eft payments take 48hrs to reflect I still contacted Edcon for an email that I can send proof of payment to. My email was never read and my payments reflect on the 3rd because my account is not updated. You are now charging me for debt collection on something that could've been avoided. I will pay and close this ******** and never ever shop at any Edcon stores!
