Cancellation request not attended to 3 weeks later because they want to keep on debiting my account.

I called in on the 19th of October to request a cancellation of my matrix tracker which i have had since 2015. i was advised to send an email to *** and was also told about the months notice period. i sent an email on the 19th of October stating my reasons for canncellatin. all i received was a reference number and no communication ever since. i sent another email yesterday and i received another reference number still no commucation almost 3 weeks since i have sent my request. the installment that i paid in October on the 25th will cover this month on November (my notice period). i dont want this tracker anymore please. and i know that you will debit my account again on the 25th of November because you are so disorganised. cancel this tracker and send me the confirmation. i have found a more reliable and cheaper offer elsewhere. 7 years later, i am so done with your company.

case number: ***8 and ***0 - no response or assistance on both.
