Deduction of debit order that was stopped

Most disgusting service received. Premiums were changed without my notice. Called about 3 people. Emailed 2 with no assistance, just respinse that they'll assist but haven't bothered to do so. Only once I enquired about price increase, do I get the increase letter dated Feb 2015. I cancelled my policy and got confirmation, I even went and stopped the debit order. Such underhand dealings and disgusting processes, they went and changed the amount so they can debit. I got an email confirming they'll refund the amount they deducted from me without consent or notice. To this day I'm still waiting. This is one company I'll never encourage anyone to use. No customer service. No answers as to what their processes are. Most disgusting experience ever having to deal with a insurer who's dealings are so underhand that they resort to changing debit order amounts just to ********ly debit my account without my consent.
