Terrible Service from Liberty Life Claims

I have a Living Lifestyle policy with Liberty Life. I had a kidney operation last year in November 2014. When I came out of Hospital, I sent through my claim to them on the 21st if January 2015. It. Its been 3 months and they still processing the claim. The Team Leader Jermaine Padiachi keeps saying to me we have not received the the PMA from my Medical Centre. I went to the medical center myself to request for the PMA. The PMA was filled in by the Doctor on the 2nd of April and a message was left for Happy Tloubatla to collect same day. Today is 19 days later and the PMA is still not collected. I sent two emails to Happy and Jermaine on the 8th & 16th of April and no one bothered to respond to my emails. Only When I called and spoke to Jamila Hassim on the 20th April 2015, that's when Jermaine responded telling me that he has not received the PMA which not true. Someone is not doing their job and they keep passing the buck to he medical center . These are the guys that debit my account every month but they here I am being treated like they are doing me a favor. This is bad customer service and its totally unacceptable. I expected better from Liberty Life Insurance
