Discovery Life Not Satisfied with the service

I opened a life cover with Discovery in June I Emailed my ID document to the person who was assisting me"Traven Govender". when i checked my Policy documents i realized he captured my names incorrectly. Actually my Preferred name was just typed as 'M' Not sure why this happened because i sent him my ID copy and would have expected him to copy the name from the ID. I have tried to update my details numerous times and my Surname still appear as Mukweho instead of Mukwevho. I have filled in all the other details myself. I Emailed Traven on the 15th of August and then called him after sending the email and he has not bothered to even reply to my email. My surname is still incorrect and it just seems like im just being disrespected here. So Annoyed!!!
