Disgusted

I have been with Bonitas for a number of years, and every month i have an issue, i have now come to a point where i am putting in a cancellation letter, I was mailed to send through 3 month bank statements for myself and my spouse, they asked for this information 2 days before the time, i send a mail stating i cannot give this information within 2 days, i never got a response, i then got a mail stating they have put me on the highest income bracket, i did send in my information before i got the mail stating i was being put on the highest income bracket, i phoned in and was then put on the new income bracket, however only last week was a given the new amount, i paid my normal premium on the 29th, they have now suspended my benefits, i feel they were late with a response, they should charge me the new amount from August only and not suspend me, due to their staff being ***********.
