Really poor customer support

My online banking profile is locked. I have tried to use their website to unlock it. I went into a branch and tried to get help there. I phoned the online banking call centre and was asked what browser I was using. I supp**** them with a screenshot showing the problem and have also supp**** FNB with the request headers of the call being made. It appears that there is a problem with their site which is all well and good but nobody at premier banking or online banking seems willing or able to unlock my profile and tell me if my bank card still works.
