Debit order deductions dispite cancellation.

On 14/09 I enquired for insurance with budget and took the insurance as it sound like a reliable insurer. A DebiCheck was done so I could approve the debit order. On that same day I sent an email canceling it as I had received a better offer with another insurer (this is within the cool off period). In October and November debit order deductions were made dispite the cancellation email sent and calling without receiving any assistance. I had disputed those 2 debit orders were reversed but it's being debited for the 3 time this month and I'm being blocked by budget from disputing this debit order therefore the bank cannot reverse it. I tried calling again today and instead I was placed on hold and the phone was disconnected there after.
