Standard Bank Stokvel Account

In January 2017 I joined a stockvel (which already started in December 2016) where we had monthly contributions of R2000 for 11 months making total contributions of R22 000. The stockvel account was opened with Standard Bank in a Cape Town Branch because the founder of the stockvel is based in Cape Town and signatories he selected when he opened the account. I am based in Pretoria. The founder and all signatories are refusing to give members the bank statement. Some members did not get anything from the Stockvel. At standard bank Pretoria CBD I was told to either bring one of the signatories or to open a case with the police so that the police could subpoena the bank to release the statement. the police told me they need a crime scene and they cant open a case for 1 person and that they need about 5 statements from different individual. I have exhausted all my option with no assistance. I have been in contact with the business banker of the stockvel account and she couldn't do anything for me. This person is using the standard bank account to **** the members and is refusing to account by refusing with the bank statement.

I need intervention.
