Its almost 3 years now and my issue is not resolved , Discovery just responds to save face

The post below is from last year in March when I got a call from a discovery representative who assured me the issue would be resolved. I gave him the reference numbers for the calls and everything I did in the past and he still came back to tell me they can see the proof I sent everything but their system still says I owe them money. I would like discovery to step up and own up to the good service they claim to provide. I pay my dues where I owe and I have provided you with proof that this is not the case but I still get calls that your system says otherwise. How does an issue drag for 3 years and still no resolution is found despite all the information being provided:

This is my last post from over a year ago

Its a month later after receiving a call from a discovery representative who responded to my complaint on Hello Peter. He assured me that he would help me or at least get back to me in due course. I asked him to provide me with his e-mail address and he instead promised that he would e-mail me and I would get the address when he e-mails me. Now I have to contact them again so that I explain my problem with them all over again. If my counting serves me right, its now six months on and a simple issue has not been resolved. To summarize, I got refunds from discovery and paid them back to the scheme as soon as they came through. I also sent them my bank statements for us to reconcile this. Now I see that I still receive automated e-mails saying that I owe them the money. It now seems like their response on this platform is to rather save face than helping their customers whom they claim to provide world class service. I need someone to help me on this, if not can someone please help me escalate this problem ?
