Poor Account Ethics at Edgars

Good Morning,i would like to raise my disappointment with Edgars regarding my store accounts(12 month account).In January 2019 my balance was +/-R 13000,00 due to the festive shopping done in December 2018.My installment was+/-R 1100,00 per month,and in March and April i had financial challenges and i paid half the amount R 600,00 and repaid the outstanding in May 2019. I am however frustrated,in that to date my balance is +/-R 4500,00 but i still get a monthly installment of +/-R 1100,00.With the installment so high i am unable to use my clothing account to buy,cause it will just escalate the installment amount.I have wrote numerous emails to their customer service,and they keep referring me to my balance of +/-R13000,00 in January 2019.In frustration i informed them due to their non understanding of the problem,i will report them on social media and pay my account till end ,and open up another account at another retailer,NO REPLY TO DATE!
