Bad service

I haven't had a problem with outsurance ever before until I recently canceled my policy. I to date have not received the full premium back from them in spite of sending my policy schedule numerous times from the other insurance company to show that I had double cover. I'm deeply disappointed I advised the consultant I am unemployed and can no longer afford the higher premiums and had no choice but to seek a lower rate, to top it off I still have not received a call back or assistance from them I get told to resend my documents every time and it's incredibly frustrating at this point! Very disappointed in the service I have recently received
