Perth ethic customer service/turnaround and no customer focus !!!

I was sent an email from Bonitas to submit my income verification. Seeing that i have been unemployed since July 2022, I submitted all docs as well as a letter stating that my husband was paying my contributions. Bonitas put me on the highest income bracket and sent me a statement where my monthly contribution was bumped up to R2900.00pm. I have been calling bonitas daily as well as emailing them, with no feedback. In March i receive a statement stating my monthly contribution has now been bumped up to R5900.00pm and my medical aid has been suspended since January 2023. I have been calling and emailing for 3 months, i am always told someone will call me back, which never happens. This is pathetic customer service. Today i made another call and was advised that someone will call me which has not happened. How can we deal with a company as such, because they put you on the highest income brakcet when you are unemployed.
