Angry poor service

On the 20th of September I put in a withdrawal, today is 30 days later. Feedback is none from Momentum. Was asked for a tax number on the 13th, received feedback it was received and my withdrawal is on the payment step, today 7 days later still no payment. Today I call speak to Bongani that promises to call me back as they were so call offline. Still waiting, phone a little later automated message says call centre closed due to training. Call back again later, speak to Carli, get put through to Michelle (the administrator) land up speaking to someone different no name given to be told Momentum is awaiting my tax number. Get told Michelle will call me because she can see I sent it, so now she does not understand what is going on. Now still no call and here I am still not knowing what is happening.
