Account closure and withdrawal frustration

Stanlib is an unsympathetic dont care attitude company with untrained callcentre consultants they advise nonsense and when you need the related parties you are given email address with auto response after 24/48 hours. My mom died in 2014 all documents where scanned and sent to them in 2014 but account was not closed as per advice. I requested the account to be closed they said I must resend the documents again of which I did. Now because there's money in the account I am given the run around a withdrawal should not take more than 2weeks. I am now forced to re-live my moms passing. I cant imagine my kids going through this, so thats why I encourage South African to choose wisely. My relationship with company and its associates is done. They claim all calls are recorded but thier employees keep tell/advising nonsense SIES MAAN. SARS is now on my case and continuous delays is costing me money but they just dont care and no follow up what so ever. How can such a big company centralise complaint,enquiries, withdrawal etc...to one email address no wonder it takes so long I AM VERY UPSET.
