FNB business account Frozen for 2nd time in a year

First National Bank has put a hold on my account, for the second time now in a space of a year. They always ask me for source of funds when ever funds are deposited in my business account by a client I am servicing and my issue now is I have sent the consultant by the name of Ntwanano Baloyi all documents he requested and still my account is still frozen but it was quick for them to freeze my account and now been sending emails to this ***** Consultant to no response, FNB is a ****** Bank indeed.
