Cancelled Due to Non-Payment (A Lie)

I received an email about the renewal of my Dotsure Cover. I responded by indicating that I will not be renewing and that I would cancel my cover as I was unhappy with the service I had received. I received a reference number and more than a month later a debit -order with the increased amount was deducted from my account. I had the fund reversed and a day later I received a notice that my policy was cancelled due to non-payment. This is false! I will be seeking cover elsewhere and if this reflects on my portfolio/profile, I will be escalating this to the ombudsman as this is a blatant lie. The Call Center advisor (Annemi Du Plessis) Confirmed that she received a notice on 1 May 2019 regarding my cancellation.
