Cancelled policy - premium still debited

I have asked mi way for business insurance ( Taxify) for my vehicle in Jan 2018 The policy was due to start 1 Feb 2018 however as confirmed by the agent I spoke too. On the 30 I found out that Taxify does not take hatchbacks on their platform and have since decided to cancel the policy. I immediately on the 31st send mi-way (the business department)an email to cancel the policy and also advise when someone would come and remove the tracker installed by C-track as I wanted to cancel. No one have emailed me back to confirm ANYTHING as a result the amount of 1600 and some cents was deducted from my wife's bank account! We want this money back as I have the PROOF that the we asked for this policy to be cancelled..I want my money back !!!!!!!!!!!!!!!!!!!!!!
