Old mutual superfund

The worst service ever. My pension fund claim was submitted on the 3rd of August and to date have not received anything but instead I was told that my address had to corrected on the 16th of August. When I called on the 18th of September I was told they were waiting for Sars. After that I heard nothing until I called again on the 11th October and only then I was told that my claim was cancelled because of a technical error. Was also told that it will only be referred to sars then and I should wait. I am so disappointed in the service I have received. Almost 60 days waiting and action only taken after I call. So that means nothing was going to be done if I had not followed up!!!!
