Frozen account and funds

My name is Alex Thembinkosi Cebekhulu I have a problem with standard bank of South Africa they have frozen my business bank account together with my money that i have worked for since September 2019, I have consulted with the bank on why did they freeze my account and they said they are suspecting that i have receive the money **********ly and they are busy with the investigation and once its done they will contact me and since then no one from the bank has ever contacted me from Standard Bank.

And i want to say i have been into contact with the bank, making some follow up trying to find out on how far are they with their investigation and they cant give me a tangible answer, sometimes they will keep me holding on the phone saying i have been transferred to the ***** department and the phone will ring until its hanged up. I have worked for my money and i also want to say that am so frustrated with the way Standard Bank handles customers issues, they can not freeze my money for such a long time and just keep quiet its almost 2 years now, i want them to release my money, because i can see that none whatsoever has been investigation underway . They are ******, they are a **** bank and i wont recommend anyone near me whether a family member, neighbour or a friend to open an account with them. They are unreliable, unclear, undependable ,************* and problematic. I just want them to unfreeze my account together with my money finish & klaar.
