Pathetic service!!!!

My premium increased without my consent??? I recently changed insurance and “Itumeleng” advised me that there would be no changes regarding premium to my trackers. To my surprise there was a change indeed. I called into your call centre and received the most pathetic service from your “leadership” they never available and always on lunch. I’m always calling them for feedback? How’s that for service??? All I want is feedback? I didn’t not approve or agree to any increases??? If I did please provide me proof( voice recordings)
