Bad Services Ever Received in my Entire Life

I had policy with Outsurance which I cancelled in October 2014 but Outsurance continued to deduct premiums from my account despite my effort every month advising them to cancel the debit order. The debit order was only cancelled 6 months later in March 2015 after I had escalated the matter to management and compliance officer. <br> <br> Following efforts with Outsurance the debit order was finally cancelled in March 2015 and was refunded the premiums. However, to my surprise I was only refunded premiums for March 2015 as well as only half the premiums since October 2014. Vernon, in his response to my email after several reminders informed me that it was the standard procedure that Outsurance refunded me a portion and the other portion should be paid by my new insurance company. <br> <br> I was never dually insured, my new insurance company deducted premiums accordingly and it is Outsurance that failed to cancel the debit order. I have been sending emails to Vernon with no response and my latest email was on 25 May 2015 of which he responded on 11 June 2015 after I sent him 3 reminders. My follow up email on even date (11 June 2015) he has not yet responded to. I want a refund of all my premiums
