Stop causing drama in my life for a 16c

I asked Neliswa why my premium is changing with 16c and she said she doesnt know so she cant explain it. Now you get Chanelle to call me who can't do a better job than Neliswa. Can Chanelle please stop calling me. She can't even explain properly and keeps contradicting herself. She says that she needs to confirm my premium and my cover that's changing. I'm asking her how my cover is changing she's says sorry your cover isn't changing. I than ask so you want to cause drama in my life for a 16c. She than contradicts herself again and says she needs to confirm my premium and my cover thats changing. I don't want my premium to change you can leave it as it is.
