FNB BUSINESS ACCOUNT ACTIVE OR NOT!

Last month i opened a new business account with FNB online, they sent me all the paperwork and KYC documents for my signature which i returned to them, they even couriered a card to me but today they cant help me. I gave a client of mine the banking details for them to make a deposit and they made a deposit last week tuesday, the 6th of August 2019, today the 12th of August 2019, i call in to enquire this transaction only to find out the FNB BUSINESS hadnt FINALISED AN ACCOUNT CREATED IN JULY, and as a result of this, the funds are now stuck, my clients bank says that the funds are frozen by FNB and will be returned in 10 days and FNB says to me that they cannot help me access these funds. As a SME, this has cause huge revenue loss as these funds were going to be used for costs. This service is unacceptable.
