Preservation Fund Claim

It's been 3 months since I submitted a request for withdrawal. In March I was provided with a form to complete and was told it would take 10 days to pay out my benefit. No feedback received. I followed up 3 weeks later and was told benefit can only payout once declaration from doctor is received as I was a disability claimant. I advised OM that my appointment with the doctor was only in July and subsequently provided them with all other documentation regarding termination of service from employer-Nedbank which also confirmed that I was a disability employee and termination of service. The same was sent several times yet no response received. If I don't call, nothing happens to my claim. I've been shoved from pillar to post and sick & tired having to wait endlessly for someone to get back to me and the excuses. I've dealt with Moses and Monezi Ntleki who promised to speed up the process but to date no feedback at all received. I'm disgusted and shocked at the lack of service, which is to no surprise. If I don't get feedback by close off business 17/06 regarding payment of my claim, I'm escalating this matter to the highest level. This is no way to treat your clients.
