Unexpected premium increase

I'm very disappointed on Vuyo funerals.financial we are all facing hard time as a country that's a fact, I just joined Vuyo for one month my premium was 415 I was happy with that, the second debit date I told I'm suppose to pay R455 how is that even possible, I'm with the company for only a month not even a year, did they even consider how this is going to affect my budget.if they plain to increase prices they should consider increasing plans that are already with them for a year. I'm very disappointed.
