Making profit out of the poor

So disappointed by miway insurance my debit bounced back because if their increamemt. Wht frustrated me is that i hv been loyalty to miway. I have never claimed any accident since 2008.last month debit was R518.16 all of the sudden now its R594.even if there is an adjustment such amount R75.84 this people are making profit unnecessary. Money thr was left in the bank was R520.now my premium is R594.worse they increase the premium as if am driving latest car.i am driving oldest car polo 2008 bt increamemt of R75.84 still shocked now they have inconvenienced me for npt getting their exact money
