BAD SERVICE FROM MOMENTUM

I phone Momentum STI to submit a claim that occurred during the Easter holidays while I was travelling to my home town. On Friday 10th April 2015 approximately 13:00pm, I spoke to a lady by the name KEAMOGETSWE HOEANE in claim department, she captured my claim and since then I have been waiting for correspondence regarding the assessment center that I have to take my car to. I have called them numerous times and the consultants there keep on telling me Kea is on the phone she's busy with someone else and she will call me as soon as she is done. Until today, no one has called me. Imagine if I have to wait almost 2 week for them just to assess the car, how long will I wait for them to process my claim... I have sent KEA emails regarding this query and she hasn't got back to me... Momentum please improve your service level...
