Uncontactable after 33% Premium increase!

I have recently put in a claim with my Insurer and received a mail the requesting proof of previous insurance. Before I could respond I received a call from Zodwa who is handling my claim requesting the info and ensuring me that she will take care of it. She rep**** a couple of days later stating she could not find the one police and I sent her a copy of the original insurance documents from the provider on 10/11/2015. My car was taken in for repairs on 18/11/2015 and is this still at the shop. Today I receive a mail stating that my premium will be increasing with over 33% from Leone. I called and spoke to someone who stated that Zodwa had loaded the instruction as she could not get hold of one of my previous insurers. I tried contacting Zodwa since 16:25 and was cut off numerous times until the switchboard closed, she has also not responded to any of my e-mails. This leads me to the conclusion that First for Woman is an underhanded corporate which waits until their clients are at a disadvantage to increase premiums and then avoids contact. I also believe that this is due to incompetence and/or laziness on part of the staff to do as they have promised. I am extremely disappointed!
