ABSA ***** payment no communication

My business account was put on hold on the 05 July, on the 06th i contacted the call centre and they said they will call me back and they did not. on Monday the 09 July 2018 i went to Wonderpark Branch and i was advised that they suspect ********** activities in my account which is the reason why my account has been put on hold and requested that i provide invoices and proof of payment for a period of 2 months.. i emailed all the required information and documentation on the same day.. on the 20 July 2018 i received an email from Tebello Rakosa and it read "Please send us a police case number and affidavit regarding the ***** matter" I responded asking which ***** matter is he referring to because i am not aware of any ***** on my account. and he has not responded to my email... the ABSA contact centre gave me the following numbers ********** 013, ********** 004 and 011 ********** of all them just ring.

Its very frustrating for me Because its almost a month now and there is no communication whatsoever from the bank and i am not able to use my account.... Is it the bank practice to hold accounts and not communicate with account holders.
