My bank account issue

I am very dissatisfied with the treatment FNB has rendered me. My account has been frozen by FNB upon numerous communication with the bank, I have received a payment into my account and the account was frozen awaiting a communication from the sender’s bank, which is ABSA bank. FNB has not communicated with ABSA bank stating their request for assistance from the bank. I have a case number as follows from FNB *** which as been provided 3 weeks ago and am yet to receive any confirmation or further communication from FNB, all requested documents (Affidavit and proof of payment with both the sender and receiver’s ID copy) have been forwarded, however FNB has not unfrozen my account, unfortunately.I am running a business and with my account frozen for unclear and bogus reasons, I am losing money. FNB you need to take your clients seriously and provide the service we are paying for.
