This is messing up my life

So August 2017 I paid my Sportscene account that was in arrears as I opened it while I was in school and wasn't working, anyway that is besides the point. I paid my account and produced a paid up letter followed up at Canal Walk branch so they sent it to "Head Office" a few months later I find out my name hasn't been cleared, after finding that out I called the call center however today I realize the problem has still not been solved 5 months later, it is clear that there is a lot of incompetence in the organization people pretend to be working as soon as you turn your back nothing is done I am fuming with anger this better be solved!
