Standard Bank not cooperating on a ***** case

I got ****med by a company called Minta Packaging I bought a detergent mixer from them. I paid my money into their account, which is with Standard bank and they never delivered the mixer. I have tried to call them several times and they don't answer my calls . I opened a case with SAPS and FNB ( whom I bank with). FNB said they were not getting a response from Standard Bank, so I would like Standard Bank to please explain why they are not attending to this matter.
