unfair treatment

i was unfairly treated by dial direct. i have a policy for my vehicles, house and home contents and in the past three weeks we've had constant load shedding that damaged my fridge and gate motor. i then claimed with dial direct and it took them more than a week to give me response for the claim and by the time they responded i had already sorted out my staff due to security reasons. then last week i get an email from them saying that my premium will be increase from R2800 to R5447.65 as from 1st Aug. where on earth has this happened doubling ones premium within such a short period? this is broad ****************. and for that matter they just sent that letter without even a breakdown of how they got to that amount as on the schedule i have that indicates how much i pay for the different items that i have insured. people must be very careful when dealing with dial direct. i called them to find out if it wasn't a mistake and they told me that its not. they decided to increase my premium because i claimed for my fridge and gate which i repaired due to the delay in responding to my claim. so it means I'm being penalised for claiming. why do i have insurance then?
