EDGARS STORE ACCOUNT NIGHTMARE!

I've had an account at Edgars since 1980. In the last +-4 months I've had endless hassles with the payment of my account every month as they told me they would activate a debit order. Yesterday I'm told by RCS that "they don't do debit orders any more, I have to manually pay each month". I have been hounded every day with sms's and phone calls saying my account is "in arrears" DESPITE numerous eft's and emails back and forth. They STILL have my old ID number of which the last 2 digits changed in +-1994. They refuse to accept proof of payment from my online banking app, it HAS TO be from the bank itself! I mean what the heck!!?? TODAY I'm closing this account which I've had for 44 years!! DON'T ever open an account with Edgar's!!!!!! I hope I can successfully cancel all the associated policies and club membership without hassles because I've heard that other clients have struggled!! I also hope that they don't affect my good credit rating!!!!!!
