Discovery Bank unable to resolve the problem with my account

Last year 18 October i complained about Discovery Bank for not been able to help me with my account, in their response i was rest assured that what ever the issue is will be resolved. Till today my issue has not been resolved, I've contacted every department non was able to assist. I think i should now request assistance from the office of their CEO maybe my voice will be heard. Dear Sir ( office of the CEO) please see all my reviews and ask serious questions as to why such a big and reputable company is unable to resolve such a small issue since from early last year. Looking forward to your response and thanking you in advance for your assistance in this regard
