Cartrack ****med me with unauthorised debited orders

I am disappointed with Cartrack. After a good working relationship they decided to **** me by debiting unauthorised amounts from my account. I was given a quote for the transfer of the device which I was happy with but to my surprise when their accounts called the amount was different with I declined the transfer and opted for the cancellation.

But to my surprise I later realised that they had debited both amounts for transfer and cancellation within a space of 5 days.

I am still yet to receive my refund which I doubt they will provide. No one is willing to assist. My email are not responded to.
