De*****ed of my Liberty pension fund!!!!

A couple of years back I worked in a company for 4 and a half years. At that time I submitted all my documents to our auditors, who in turn submitted to Liberty to register a profile for my for my pension fund. They sent a summarized calculation sheet (Member benefits and costs schedule), containing my personal detail and fund value. Immediately upon this, I saw that my initials and surname were correct, but the incorrect date of birth was captured. My auditor resent my ID through to Liberty to amend and they assured us that the details were updated. Upon me leaving the company after 4.5 years, my fund value was as if though I had only paid for 2 months. I paid around R 450 per month based on my salary then. When my pension fund claim was submitted, they advised that after all fees were deducted, a mere +-R400 was due back to me..What a shame..I was de*****ed of my pension fund, someone registered a wrong ID number to my profile and I would later come to find that all monies paid towards my pension fund was not there...I was not given any feedback thereafter..Not one call from Liberty was made to me to get my full fund paid out to me. I was de*****ed of my own pension fund money!!!!!!!!4 and a half years, I paid to about R 450 per month to only get back less than R 400 after my contract ended!!I sent an online enquiry the other day, enquiring on this matter, but no response...I know I will not recommend anyone to use of their services!!!
