FNB is pathetic!

This is now my third post regarding the same issue yet it still goes unanswered and unresolved. Two weeks ago my Cheque account was frozen without my knowledge or a warning from FNB. I contacted your call center and was told proof of address is required. I then get transferred to Simon in your premier card department who advised that the hold on my account has been lifted and no documents are required. To my surprise on Saturday my account was once again frozen. I explained the situation here and was contacted by your wonderful hello peter department twice who have been of no assistance since Saturday with regards to my bank account been frozen. My complaint and query is being investigated and transferred to every freaken dept within FNB without a resolution. Yesterday I contacted FNB and was told my account is frozen as they now do require proof of address, despite what was told to me 2 weeks ago by Simon. I sent in my proof of address yesterday. Can someone that actually knows what they doing escalate this to someone in head office so that this issue can finally get resolved. Surely you have an escalation channel instead of not getting back to me or telling me the matter is still under investigation after I was told what is required and documentation has been sent. I do not want a call from your hello peter dept saying they have received my complaint and they are yet again sending it elsewhere! I HAVE ABSOLUTELY HAD IT WITH FNB NOW,the service I have received is disgusting. I have previously asked for a SENIOR MANAGER to contact me but that also could not get done. I have no access to my account but you guys can take my account fees off with no problem.. I will definitely go post my numerous complaints on all forms of social media as this hello Peter thing doesn't get any results! I want my proof of address reviewed today and my account unfrozen before close of business today!
