Blocked account

They blocked my account without any communication mid May, I went to the branch to log a quirie. I was then told to make an affidavit stating where I am getting the funds, because my account is under investigation but wasn't explained why though I asked. I did as told. My policies can't debit but they keep taking their monthly fees while I don't have access to my money. If I don't call or send tons of emails they keep quiet. June is almost ending and my policies are going to lapse if they don't get any funds again this month. The last agent to get a breakthrough was Thabiso Maleka, he got me a reference number to track with. But Standard bank doesn't reply to any of my emails unless I mention the matter on twitter they promise me a ***** consultant will call everytime but no calls received. Please help me unblock my account
