Cant stick to promises made

I cancelled my policy with Outsurance and was told i would receive my premium back on the 15th of June. Today is the 22nd and still received nothing so i called them, now they telling me it takes 30 days to process the refund! This is ridiculous, it doesnt take 30 days for them to process taking the premium! I now used other money i had expecting my premium back on the 15th and now i am stuck, that money was to go towards getting my petrol for the week until pay day, do you expect me to go to my employer and tell them i cant get to work as you guys didnt pay me my money back!! Your call centre lady told me i will get my money the 15th, now somebody better make a plan and give me MY MONEY back this week and not the 2nd of July! I work in an industry where we deal with insurance companies and their clients, this is disgusting and pathetic!
