Edgars Statements / Billing

In the middle of August 2018, I paid for my spectacles at Torga Optical, using my Edgars card. The amount was R5400. At the time I had a zero balance, hence the reason for using my Edgars card. I seldom use this account and keep it open purely to maintain a credit record, which is also the reason for the minimal use of this account. At no point was I asked whether this is over a 6 or 12 month period. My first statement arrived for end of August with a zero installment. My second statement arrived with a minimal installment, of which I paid more for at the end of September. Although I have been regularly paying my account, in fact more than the required installment as per my statements for the past few months, at the end of February this year I suddenly received a statement with an installment that was 4 times the amount. I phoned Edgars to enquire why I suddenly had this massive installment, and was then told that its a 6 month account, and the balance must be paid over a period of 6 months. If this is the case, then Egdars, please explain to me why your billing system is not in line with this policy. Every month I paid more than the required instalment, but not once was the installment adjusted based on the balance over a 6 month period. In fact, not one of the instalments calculated from your system for the past 6 months was anywhere close to a 6 month instalment based on the balance in August. I dont write my own statements. This is an automated function from your systems. I am now getting calls from your accounts dept to find out when I will make payment as I only paid R500 of my supposed required installment of R1353.34, based on my R2458.61 balance (thats and instalment at more than half the balance!!!) I would like to know, If I have been diligently paying my account with more than the required installment every month, based on statements sent from yoursevles, why am I now being penalised for paying that same installment? I have not NOT paid. Sort out your billing and statements. Its people like me who try to maintain a good credit record, who now has to fight to keep that record clean, all because Edgars cannot get their billing right. Set up your systems in- store or with places like Torga optical your are affiliated with, to ensure that if its a 6 month account, that your statements reflects 6 equal instalments over a 6 months period, based on the balance. The people who call from the call centre are also so rude, and clearly not interested nor understand how billing and statements work. All they interested in is reading from that piece of paper they themsleves done understand and wanting to know when I will pay. There is so much emphasis on "these calls are recorded", but the calls can never be found when its needed. SORT OUT YOUR BILLING SYSTEMS EGDARS.!!! A telephonic policy is worth nothing if nothing else is aligned to that.
