Standard bank holds my money for no reason!!!

I had money that was paid into my account on the 5 November and at the time my bank account had been closed as it had been inactive for a year. I re-activated my account on the 7 November and standard bank advised me that the money must have bounced back to the person who paid me. Four weeks later the money has not bounced back and the person who paid me advised me that Standard bank is holding my money. I have sent all the necessary information and I just want my money released. I have been told that this is a popular thing with standard bank holding peoples money. If this is the service one gets, there are so many other banks that one can use.
