Edcon -Jet invalid billings

Truly upset. I emailed Edcon on the 13the of April 2018 asking whom authorised a Jet save club fee on my account. I received a mail back two days later stating they will escalate. Guess what it is year later and they are still billing me and I forwarded my previous mail asking when they will reverse this as I did not authorise it and yet again I receive a email they will escalate. I want to open a ***** case as I have been paying for a service not requested over 7years already. I tried to phone them yesterday but the phones just stay on the music tone as if they are so busy and can’t sort out the account. I want the credit passed and my account closed. Sick of people doing what ever they want.
