FNB poor service of a ***** suspected suspended account

First National Bank has not yet responded to me over the ***** suspicion case that made them to free my investment in their share saver. My investment in share saver has no connection to the suspected ***** but FNB still suspend my account. On the 14th of September they promised to respond to me within 24 to 48 hours from ***. And up to today, I got no call.
