Budget *****ing my money

I called budget to cancel my car insurance policy in March but I was still debited. I called to find out why I was debited and ask for a refund and I was told that the refund would be in my account in 7-10 working days. When I called 10 working days later to find out why I hadnt received my refund, I was told that my policy was only cancelled when I called for my refund. I have called multiple times since then and ran out of airtime on a couple of occasion. I asked for a call back twice but on neither occasion was I called back!! On the latest occasion, the lady told me she needed to chat with her manager and would call me within the hour but it has been 2 days without her calling me back. I want my refund and I am going to the insurance ombudsmen after this as well. Truly disappointed in budget
