Bad Service

Dear sir, I have a business acount and peronal account with FNB clients have paid money into my personal account which FNB income verification put on hold. They wanted the customer invoices and a letter from the customer to authenticate those funds. Whether its my business or personal, it is still my money. I have been struggling to get hold of the people whoare responbile to issue me with a leterr, but I have the proof of payments. Once this is sorted outed out I am going to close both these accounts and use NEDBANK. Thank you Ali Zorkot
